Tommy 46%, Tammy 45%.

In the new Marquette University Law School poll.

In the last Marquette poll, released Oct. 3, Baldwin led Thompson 48% to 44%, but her advantage was half the size of the 9-point lead she had in a Marquette poll two weeks earlier.

How did Tammy ever get out in front? She's the most liberal member of the House of Representatives. Tommy's old and was perhaps too lackadaisical about what it would take to win, but still.

Also in the new poll: Obama 49%, Romney 48%.
