I didn't think he'd bow out, but it's all over Twitter that Paul Ryan has told his closest associates that he won't run for reelection.
Ryan's expected to make a formal announcement to House Republicans later today.
Maybe it was the #ToxicTrumpEffect or maybe it was the prospect of losing reelection to the #IronStache. Either way, this opens the door wide for either steelworker Randy Bryce or schoolteacher Cathy Myers. A Democrat can win this congressional district.
No sudden Republican retirement from Congress will hit the GOP harder than this one.
