If they can get 15 or higher, it will be a very bad night for House Speaker Paul Ryan. Ryan twisted himself into a pretzel by endorsing but not always supporting Donald Trump. Now, he's facing the prospect of a slimmer majority, with fewer moderates. Conservative members in the Freedom Caucus have already sent warning shots threatening Ryan's tenure as speaker.

Even if [Donald] Trump concedes, some of his supporters have promised to take up arms against [Hillary] Clinton.

Both the Obama and Romney campaigns said they pulled all their political ads today in observance of the September 11th anniversary. But politics wasn't very far offstage. The Obama campaign sees foreign policy as an advantage this year.

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

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

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

Donald Trump is a candidate who divided his own party more deeply than any presidential candidate has before.
