Senate GOP Braces for More Retirements

Politico: “The effort to retain Republicans who have won races in tough states came into focus on Monday when Sen. Rob Portman surprised Republicans by announcing he won’t seek a third term in Ohio. Republicans will still be favored in the Buckeye State but will now have to contend with a primary that already looks crowded, with a laundry list of Republicans considering or already taking steps towards running.”

“And there’s already concern that more could join him in running to the exits as the GOP prepares to serve in the minority for the first time since 2013. Next year’s Senate map has enough swing states that Republicans could retake the majority — but they could just as easily lose more seats.”
