If [Donald] Trump wins narrowly, Democrats can blame the loss on FBI director James Comey, who inserted himself late in the campaign in an unprecedented way.

Donald Trump's staffing up a pretty traditional, very conservative Republican government, not a populist outsider government, at least not yet.

For Democrats, anything less than 15 net pickups will be a disappointing outcome [in presidency race].

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?

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.

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.

[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.
