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

If Pat Toomey of Pennsylvania wins, for instance, it will tell Republicans that their own brand hasn't been hurt too badly by [Donald] Trump's negatives.

In 2012, African-Americans were 13 percent of the electorate, and 93 percent of them voted for [Barack] Obama.

Well, we had a bunch of primaries and caucuses on the Democratic side. Bernie Sanders won the Nebraska and Kansas caucuses. That keeps his campaign alive. But Hillary Clinton won Louisiana, which was the big prize of the night, so she ended up winning more delegates than he did yesterday.

If [Hillary] Clinton can come close in those two traditionally red states, it will be because of the diverse, educated populations around Atlanta and Phoenix. And it will be a sign that Arizona and Georgia are on their way to becoming the new battleground states.

For a long time, many Republicans thought if they just took two aspirin and laid down, [Donald] Trump would go away.

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