Democrats' New Best Friend?

Sen. Scott Brown (R-MA) turned some heads when he voted, along with four other Republicans, in favor of Senate Majority Leader Harry Reid's jobs bill...well, actually just for cloture on the jobs bill, but, the way the Senate is working now, with every big initiative under the threat of filibuster, a vote to proceed to a vote is about as good as a vote on an actual bill.

But does this mean Brown is Democrats' new best friend in the Senate--someone we'll see them working with consistently as a gettable vote, along the lines of moderate Sens. Olympia Snowe (R-ME) and Susan Collins (R-ME)? The Atlantic Wire's Heather Horn looks at responses to this question and finds that, while there is some optimism, bloggers are generally skeptical that this will be the case, warning Democrats not to get their hopes up.
