New today: House Speaker Paul Ryan won’t run for re-election, a decision whose timing was first reported by Axios’ Jonathan Swan. Rep. Dennis Ross (R-FL) is also retiring, the Tampa Bay Times reports.
By time the midterm elections roll around, there will be at least 58 vacated House seats up for grabs — two-thirds of those are currently held by Republicans. The openings are significant because incumbents have outperformed non-incumbents of the same party in similar districts by about seven points in the last decade or so, per the New York Times.
