Republican voters are coalescing behind [Donald] Trump, but many Republican elected officials still say they can't support him.

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.

Hillary Clinton has had a small but persistent lead since June - anywhere from 2 to 5 points. The stock markets and the election betting pools are predicting a Clinton win.

If [Hillary] Clinton wins, history will also be made: She would be the first female U.S. president, of course, but also the only candidate in the modern era, other than George H.W. Bush, who managed to follow a two-term president of her own party.

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

I think that's why we see this mixed reaction - Republican congressional leaders like Paul Ryan speaking out very firmly, but Republican candidates not as much, with the exception of the candidates in the single digits like Jeb Bush or Lindsey Graham, who said how to make America great again tell - Donald Trump to go to hell.

Until he announced his immigration policy last week, Obama had the support of most Hispanic voters - but not the enthusiasm they had shown for him in 2008. That may be changing in part because of the decision not to deport young immigrants whose undocumented parents brought them here as children.
