Fine by me for her to remain the leader and face of the party - she is one of the least popular public figures and we can continue to use the line in ads saying Democrats “voted with Nancy Pelosi 90% of the time”, etc. Let her continue to be out front and devisive.
The 'Rats can't stop anything in the House -- even if they stick together.
But, as you point out, she remains campaign fodder. She can now be the face of "The Party of 'No'" -- and her face will make the claim believable.
