MADISON, Wis. (AP) -- Who wins the "Tammy vs. Tommy" U.S. Senate race may come down to who is better at convincing voters that their opponent isn't who they appear to be.
Both sides and their allies broke spending records driving home messages trying to paint Democrat Tammy Baldwin as an extremist and Republican Tommy Thompson as someone who's not for Wisconsin anymore.
The infusion of nearly $50 million on mostly negative television advertising dominated the tone and tenor of the race.
Now with the race in its final days, who actually wins will be dependent on several factors. Among them are who can turn out their voters better, who independent voters ultimately side with and whether voters will accept the narratives pushed by the campaigns.
Polls show the race is a dead heat.
