But there’s an even more significant story going on here: The non-Trump wing of the Republican Party wants out.

Think about the other GOP retirements we’ve seen — Reps. Susan Brooks, R-Ind., Martha Roby, R-Ala., and now Hurd.

And these Republicans parachuting out of the Republican Party underscore how vulnerable Trump really is, despite the growing economy.

The fewer Will Hurd-like members running in 2020 reduces the number of moderate/non-Trump Republicans who would eagerly go to the polls for those representatives – and then still hold their nose and vote for the president.

The Republican Party is getting smaller and smaller, and that isn’t good news for an incumbent Republican president.
