Trump's ominous loyalty demands

You saw this two years ago, one year ago and still today in the vast majority of Republican voters having his back through good times and bad.

Why it matters: Soon this could matter in consequential — and constitutional — ways.

With Democrats taking the House, Trump can anticipate impeachment proceedings — and knows that all it takes to save him is the loyalty of Senate Republicans, regardless of the evidence.

The chance of Trump needing the Senate — and perhaps the Supreme Court — to side with him on big legal matters flowing from various investigations is high. It certainly won’t hurt that he put two justices on the court, and a lot of men in the Senate.
