What if he says [Donald Trump] plans to run again in 2020?

Well, we had a bunch of primaries and caucuses on the Democratic side. Bernie Sanders won the Nebraska and Kansas caucuses. That keeps his campaign alive. But Hillary Clinton won Louisiana, which was the big prize of the night, so she ended up winning more delegates than he did yesterday.

Obama's even keel sometimes comes across as aloof or even cold.

If she Hillary Clinton win just two of the three big battleground states - North Carolina, Florida and Virginia - she will have shut off Trump's path to 270 electoral votes, even if he wins the other toss-up states.

[Donald Trump ] would make history in so many ways because he is a candidate who eschewed the traditional arts of political campaigns, including field organization, traditional advertising, debate preparation and policy knowledge.

Republican voters are coalescing behind [Donald] Trump, but many Republican elected officials still say they can't support him.

In 2012, Hispanics were 10 percent of the electorate, underperforming their share of the voting-age population. Mitt Romney got 21 percent of their vote, and [Donald] Trump has been polling much lower than that.
