Wisconsin's hyper-competitive U.S. Senate race looks like it will come down to the wire, according to a poll released Thursday.

The latest poll from NBC News, Marist College and the Wall Street Journal shows Rep. Tammy Baldwin (D-WI) barely edging former Republican governor Tommy Thompson 48 percent to 47 percent. Baldwin held a slightly larger 4-point lead in the previous NBC/Marist/WSJ poll in mid-October.

The PollTracker Average shows Thompson closing in on Baldwin, who built up a sizable lead in September.
