CHRIS STIREWALT: Sanders Trumps Hillary:

If Sanders can pack nearly 30,000 souls into a Portland, Ore. arena it’s fair to say that he is doing even better than Trump into harnessing the outrage that animates voters, particularly older, white ones, who believe that America is truly at the abyss. And remember that both Trump and Sanders share the view that a conspiracy between business and politics is at the core of the problem.

It may be Portlandia, but still…

The biggest difference between the Democrats and the Republicans, or between Clinton and Bush, if you prefer, is that on the GOP side there are lots and lots and lots of viable alternatives. As Thursday’s debate showed, Republicans have plenty of credible choices with reasonable electoral paths.

If Col. Sanders’ army succeeds in either scuttling Clinton’s nomination or pushing her so far to the left that she can’t scamper to the center next year, there’s no place for the party to go.

Stay tuned.
