You can't answer that question without knowing what the balance of power count is in the Senate. If they are the 61st and 62nd Republican vote, respectively, then no, they aren't worth the trouble.
But, when you're already spotting the opposition 10-seats to parity, then YES, they're worth the trouble.
I seriously doubt Maine will ever get it’s act together and toss these two onto the street...
What a pathetic shame...
