They Release Statements

According to a press release from Valerie Martin, Rep. Allen's campaign manager:

Two of Monday's missed votes named post offices in other states. The third honored a National Guard unit from another state.

If this is true (and as far as I know, the Maine GOP hasn't produced any information to the contrary) then the Collins campaign is indeed guilty of launching a cheap shot attack on Allen.

Look: It's important for legislators to show up. But the job of a representative is to advance the interests of his or her constituents--not to a pursue perfect attendance record as an end in itself.

If Sen. Collins thinks attendance matters above all else she should say that. If she thinks this election should turn on the fate of legislation naming out-of-state post offices, she ought to explain why.
