Sen. Rob Portman (R-OH) just announced that he won't be running for a third term. How do you think this will impact the 2022 midterms? Does his decision say anything about the state of the GOP?

[Politico](https://www.politico.com/news/2021/01/25/rob-portman-wont-seek-reelection-462146) broke the news that the former Ohio Representative, and Bush-era Trade Rep and OMB Director won't be seeking a third term in the Senate, citing "partisan gridlock" as the main motivation for his foregoing reelection.

Portman isn't part of the most vocal people in the Senate, but he's considered to be one of the more effective legislators in the chamber and was often seen as a potential swing vote despite voting with Trump 88% of the time, per [538](https://projects.fivethirtyeight.com/congress-trump-score/).

Ohio has been trending red over the years, so I think Portman would have had a good shot at winning reelection after winning in a landslide in '16 despite polls showing a close race.

Considering how GOP-friendly Ohio has become in the past few years, do you think Portman's retirement will put his seat in play? If so, who do you think is likely to run for his seat (both GOP and Dem)?

Is this further proof of Trump's grip over the GOP? Is there a chance Portman was concerned over a potential primary challenge?

Lastly, do you think this has any bearing on Portman's vote in Trump's Senate trial?
