There's disgust with what people called a broken political system, and they're really angry at elites, whether it's the Republican establishment or particularly the media who they feel look down on them, tell them they're bigots.

No one is predicting that the Democrats will get the 30 pickups they need to take back the House majority.

The winner's margin of victory also matters. If it's a squeaker, that will make the lessons learned for both parties much murkier.

The Democrats pulled out one of their most powerful surrogates - and no, it wasn't President [Barack] Obama. Beyoncé showed up at a GOTV rally in Cleveland, joining her husband, Jay Z, and Hillary Clinton.

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.

[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.

Hillary Clinton is also not a very exciting, inspiring candidate to a lot of the left-leaning Democratic base, especially in Iowa.
