I think republicans are shooting themselves in the face by attacking Pelosi. By all means, please try to convince the democratic caucus to nominate a new leader, maybe someone who is not 70+ years old, and has decades of experience finding congressional compromises.
Every single person who might conceivably replace Pelosi is MORE liberal than she is. Every democrat in congress who has said they will support a different person for speaker is trying to move the party left, towards more progressive values. Pelosi, the ever-practical centrist, may be the only thing keeping the democrats from going full blown crazy extremist the way the republicans already have.
You know who is even more unpopular than Nancy Pelosi (29% approval)? Mitch McConnell (24% approval).
So go ahead, republicans. Convince the dems to let Pelosi finally retire. You're not going to like whoever takes her place any better.
Wait a second, maybe that's the point? Maybe the whole goal of the anti-Pelosi movement is to deliberately sow further polarization, to divide the nation even further? Down with the centrist, long live partisan bickering? Maybe we should be checking for Russian fingerprints on those anti-Pelosi ads, because this strategy would fall right in line with the rest of their efforts in US politics these days.
