As those states and others in the South and West become more diverse and educated, they will become harder for the Republican Party - in its current form - to win.

Mitt Romney got 59 percent of the white vote in 2012, considered by many to be a high-water mark with this demographic group. Can [Donald] Trump win a higher share of white voters than Romney and get more of them to turn out?

Democrats came into the race with a structural advantage in the Electoral College. Their big blue wall - the states that Democrats have won in the past six presidential elections - gave [Hillary] Clinton a strong base to build on.

[Donald] Trump's path to victory depends on getting historic levels of support from white voters, and particularly large numbers of white, non-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.

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

If [Donald] Trump drags down a bunch of Senate Republicans, the post-election GOP assessment will be much more pessimistic.
