The would-be Bernie Sanders vs. Donald Trump throwdown will only live on in the minds of comedy writers.

The National Academy of Sciences — probably the country's most prestigious scientific group — has reaffirmed its judgment that GMOs are safe to eat. But the group's new report struck a different tone from previous ones, with much more space devoted to concerns about genetically modified foods, including social and economic ones.

Bernie Sanders and Hillary Clinton appear to have split victories in the Oregon and Kentucky primaries Tuesday night.

With all counties reporting in Kentucky, Clinton was leading Sanders by a narrow margin of 1,924 votes out of more than 450,000 cast. Secretary of State Alison Lundergan Grimes told CNN that Clinton was the "unofficial winner," but the Associated Press said the race was too close to call.

Bernie Sanders won the West Virginia Democratic primary on Tuesday over Hillary Clinton.

The Vermont senator's victory bolsters his decision to stay in the race even though the delegate math is heavily in Clinton's favor. Sanders won Indiana last week and could win several other states slated to vote this month.

How many times must it be over before it's really over?

This time, the endless 2016 presidential primary looks truly over, so long as you're a Republican.

The Republican Party will not name its nominee until July in Cleveland, but the last suspense went out of the contest Tuesday night in Indiana with Donald J. Trump's latest romp over his last serious competitor.

The Indiana voters shook up the presidential race Tuesday night, with Ted Cruz ending his campaign after a disappointing loss to now-likely GOP nominee Donald Trump.

Bernie Sanders also bounced back after a string of primary losses with a surprise win over Hillary Clinton. But the Democrat's 5-point win still won't be enough to close the yawning gap between the two.

Cruz exit clears the way for likely Trump nomination

Donald Trump and Hillary Clinton took definitive steps toward solidifying their respective party's presidential nomination on Tuesday, making their rivals' task to beat them nearly insurmountable.

Trump won all five of the delegate-rich GOP primaries in Connecticut, Maryland, Pennsylvania, Delaware and Rhode Island. Clinton notched four victories in Maryland, Delaware, Connecticut and Pennsylvania, while Bernie Sanders won the Rhode Island Democratic primary.

Donald Trump and Hillary Clinton notched important wins in their respective presidential primaries in their home state of New York on Tuesday night, helping both in their efforts to clinch their party's White House nomination.

In the Republican race, the billionaire real estate mogul sealed a massive victory over his two remaining rivals, sweeping at least 89 of the 95 delegates up for grabs.

The Associated Press reports:

Donald Trump is now the only Republican candidate with any chance of clinching the nomination before the convention.

Democratic voters in Wyoming have decided: Sen. Bernie Sanders has won the state's caucuses, according to The Associated Press. But the victory over Hillary Clinton will not ensure Sanders more delegates. The state's 14 delegates will be split evenly between the two candidates.

​Hillary for America Campaign Manager Robby Mook released the following statement on Clinton's tie in pledged delegates in Wyoming:

Ted Cruz and Bernie Sanders won the Wisconsin primaries Tuesday night, an important step for both candidates as they look to stop their leading rivals and close their delegate gaps.

For the Republican Texas senator, he's on pace for a nearly double-digit win over Donald Trump, increasing the likelihood of a contested Republican convention this July in Cleveland.

There's a lot on the line for both parties in Tuesday's Wisconsin contest. For Texas Sen. Ted Cruz, the state is a prime chance to stop Donald Trump and complicate the GOP front-runner's path to the nomination. For Bernie Sanders, a win over Hillary Clinton helps close his delegate deficit and gives the Vermont senator new momentum heading into the next stretch of the primary calendar.

Bernie Sanders swept all three Democratic caucuses that were held on Saturday, according to the Associated Press.

He took each state by a striking margin. In Washington state — the biggest prize for Sanders, where 101 pledged delegates were up for grabs — Sanders won with 73 percent of the vote.

In Alaska, with 16 pledged delegates were at stake, Sanders won with 82 percent; and in Hawaii, with 25 delegates, the senator from Vermont won with 70 percent.

Bernie Sanders and Ted Cruz each notched victories in Tuesday's Western contests, but Hillary Clinton and Donald Trump's big wins in Arizona still mean their overall delegate lead won't change much.

On the Democratic side, Sanders won big victories in the Utah and Idaho caucuses, but the much smaller prizes could end up netting him roughly the same number of delegates Clinton will get from her Arizona win.

White House hopefuls are heading West on Tuesday as both parties face voters in Arizona and Utah, while Democrats will caucus in Idaho.

For Republicans, it's another chance to try to stop Donald Trump's mounting delegate advantage, and the states voting Tuesday aren't necessarily the friendly terrain he has been used to.

The GOP presidential field dropped by one candidate on Tuesday night, but Republicans are still no closer to uniting behind a nominee.

Democrats, however, did get more clarity as Hillary Clinton racked up more wins over Bernie Sanders, extending her delegate lead and complicating the Vermont senator's nomination calculation.

The results from Tuesday's four primary and caucus states are in: three wins for Trump, one each for Clinton and Cruz, and one surprising, narrow victory for Sanders.

Bernie Sanders' tight win over Hillary Clinton in Michigan is the biggest news out of Tuesday night's presidential nomination races. Though Clinton had led consistently in recent polls, Sanders won by less than 2 percentage points with 99 percent of precincts reporting.

Ted Cruz and Donald Trump split victories on Saturday, with the Texas senator posting big wins in the Kansas and Maine GOP caucuses and the real estate mogul winning the Kentucky caucuses and Louisiana primary.

In the Democratic race, Vermont Sen. Bernie Sanders notched victories in the Kansas and Nebraska caucuses, while former Secretary of State Hillary Clinton won the Louisiana primary.

The Republicans: Cruz emerges as leading anti-Trump candidate

Hillary Clinton won the South Carolina Democratic primary on Saturday, notching a decisive win in a state where she suffered a devastating loss just eight years ago.

The Associated Press called the race for the former secretary of state over rival Vermont Sen. Bernie Sanders just seconds after the polls closed at 7 p.m. ET. With all precincts reporting, Clinton beat Sanders by nearly 50 points, winning 73.5 percent to 26 percent.

Donald Trump has won the Nevada Republican caucuses, giving the billionaire his third victory in two weeks and a huge surge of momentum heading into Super Tuesday.

Florida Sen. Marco Rubio held a narrow but decisive lead for second place over Texas Sen. Ted Cruz. With all caucus votes in, Rubio had 23.9 percent to Cruz's 21.4 percent, according to the Associated Press.

But it was Trump who towered above his two top rivals, nearly doubling the support of his nearest competitor with 45.9 percent of the vote.

Donald Trump has won the South Carolina primary, while Florida Sen. Marco Rubio appears to have edged out Texas Sen. Ted Cruz for second place.

"There's nothing easy about running for president, I can tell you. It's tough, it's nasty, it's mean, it's vicious, it's beautiful," Trump declared to his supporters at his victory rally in Spartanburg, S.C.

Trump took 32.5 percent of the vote, while Rubio and Cruz were nearly even with 22.5 percent and 22.3 percent, respectively.
