There was tremendous animus to President [Barack] Obama. Many of people said he was un-American, not a Christian and worse.

Does Donald Trump accept the results and concede graciously, pursue legal action, or tell his followers to take to the streets?

White voters were 72 percent of the electorate in 2012, and their share of the population has shrunk a couple points since then. [Donald] Trump has had trouble winning certain segments of the white vote, such as suburban women and college-educated voters.

Republicans think that [Ted] Cruz would be like Barry Goldwater. He'd lose in a landslide and pull the party down with him. They'd lose Senate and House seats.

Many people feel he did cross a line in a way he hadn't even done before and also that Republicans had to speak out because they believe Trump poses a danger to the party.

Michael Rubio said Trump's plan was impulsive and not well thought out. The other thing that's really annoying Republicans is that this was supposed to be their great week. The president gave a speech on terrorism that was not well received. They were working hard to tie Hillary Clinton to the president. Then along comes Donald Trump, and the story changes dramatically.

I think that's why we see this mixed reaction - Republican congressional leaders like Paul Ryan speaking out very firmly, but Republican candidates not as much, with the exception of the candidates in the single digits like Jeb Bush or Lindsey Graham, who said how to make America great again tell - Donald Trump to go to hell.
