This is why Nan resisted impeachment for so long.
Nan opposed impeachment for a long time, then capitulated. Smart move on her part. The newbie House members like AOC were a thorn on her side. She knew Trump was going to win the next election. Therefore, have an impeachment hearing which is a failure. The blame will be put on the AOC contingent , thereby weakening their position and negotiating ability. Pelosi will still be speaker without the aggravation of the AOC crowd, as their influence will be gone after their impeachment push failed.
