I don't have much respect for Nancy Pelosi's wisdom, but she at least understands that further impeachment votes and especially voting to impeach Trump would be playing into Trump's hand. And that Trump is not like other R "leaders" who would refrain from using such an opportunity. Further, I think the ordinary Dem-on-the-street understands this to a significant degree and pound their heads on their tables when they hear Dem "leaders" spouting this rhetoric.
BTW, FauxMex Bobby, Doh!-Mayor de Blase', Kammy, and Castro all called for impeachment, with Bennet-the-Obscure, Spartacus, and Hickenloopy making vaguely impeachy noises.
