After months and months at the top of the polls, there is a real possibility that Donald Trump could be the nominee.

As those states and others in the South and West become more diverse and educated, they will become harder for the Republican Party - in its current form - to win.

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

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.

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

[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.

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