Republicans WANT Nancy Pelosi to be the face of the Democrat Party. Why would a GOP candidate even suggest that someone other than that bug-eyed dingbat could be the Democrat leader in the House?
If the other side is in-fighting, use it. The ones who are against Pelosi are the ones to tie to her. Make them disavow or embrace her in public. They oppose her because she’s not radical enough. They have to either go way too far left to win or embrace the unpopular witch.
