MADISON, Wis. (AP) -- Democratic Senate candidate Tammy Baldwin is lashing out at Republican Mitt Romney's debate performance, saying he wants to "Etch A Sketch" his past.
Baldwin spoke Thursday before President Barack Obama took the stage before 30,000 people on the University of Wisconsin-Madison campus. University police provided the crowd estimate.
Baldwin is locked in a tight battle for Wisconsin's open Senate seat with Republican Tommy Thompson.
Baldwin says Americans saw a clear contrast between Obama and Romney during Wednesday night's debate. She says that while Romney is rewriting his past, Obama is focused on moving the nation's economy forward.
Baldwin also drew loud cheers when she mentioned Wisconsin's history making things like paper, ships, and "cheese, brats and beer."
Retiring Sen. Herb Kohl also appeared at the rally.
