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.

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

The aftermath of this extraordinary election [2016] could be just as surprising as the race itself.

People like Ted Cruz, who has tried to position himself as the best second choice for [Donald] Trump supporters, wouldn't condemn him.

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

If [Donald] Trump loses narrowly, it will make it much harder for the GOP to unify. Under that scenario, the Trumpists are likely to argue that the election was lost because the Republican establishment failed to rally around the choice their own voters made.

African-American voters are not nearly as enthusiastic about [Hillary] Clinton as they were about [Barack] Obama.
