I think that Sherwood should retire.
No argument there. If he remains, we will needlessly lose this seat (and no 'Rat has won it since Stanley Prokop in 1958).
Ditto. Sherwood needs to be taken out in a primary. If Sherwood is running for the general election it will depress GOP turnout. Such vote depression in the district could have an adverse effect on Sen. Rick Santorum next year.
