@Finn dAbuzz,
Republicans should let him sink under the weight of the scandal, rather than try to push him out. Piling on as Repubs did with Clinton will only give him cover and generate sympathy for him. On the other hand, allowing him to hang around will be an on-going albatross around Dem necks...
At this point, especially with the precedent of Repub Chris Lee resigning immediately for far less explicit photos than those we've seen so far, the Dems are between a rock and a hard place. Any pretext of Dems (and Pelosi) holding the high ground of ethics and morality (remember Pelosi's promise of the most ethical congress...?" is irretrievably broken until he goes. Dems realize this so I think Weiner will be gone before the end of the month.
