Why GOP leaders should be scared

Only one poll number to remember this week: WSJ/NBC finds that Trump has 98% approval with Republicans who voted for him in both the primary and the general.

Be smart: Don't underestimate Trump's power to do whatever the hell he wants and still keep his base voters. If they stayed with him through Charlottesville and "Access Hollywood," they're not going anywhere over a Beltway deal.

Trump has an almost magical hold on his voters. He makes regular deposits in the Bank of Base, and has a nice balance.
