If Donald Trump wins, it will be a seismic event.

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

If the Congress is going to spend its whole time hauling up regulators and bureaucrats and looking like they're focusing on tiny, trivial things, instead of jobs and the economy, it could be a problem for them.

On the other side, you have the conservative intelligentsia - magazines like National Review, which has a big anti-Trump issue; Weekly Standard editor, conservative talk show hosts - they're mounting a big anti-Trump effort, pro-Cruz effort because they think [Donald] Trump is dangerous and he's not qualified to be commander in chief.

The base has chosen or is choosing a candidate that the establishment says is absolutely unacceptable. And what that means is this marriage of an elite, big business-backed establishment and a blue-collar, downwardly mobile base has really come to a divorce.

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 has said he wants to keep Medicare and Social Security the way they are. Congressman Price along with most Republicans are on record supporting voucherizing Medicare. So there are going to be some conflicts to resolve there.
