This is the new ad Bill Foster is running against Judy Biggert, which in part hits the Republican incumbent for being in Washington too long.

The race between Biggert and Foster for the 11th congressional district is among the most closely watched in the state. Foster, once an incumbent himself, is trying to unseat his opponent, who the Democrats see as particularly vulnerable.

A new poll by the HouseMajorityPAC shows Foster up slightly with 49 percent and Biggert with 45 percent. The margin of error is +- 4.9 percent though, so it's a statistical dead heat.

The two are to meet up on WTTW's Chicago Tonight 7 p.m. Wednesday for a televised debate.
