WASHINGTON (AP) -- In addition to the presidential prize, every seat in Congress is up for grabs and about one-third of the Senate.
Democrats are hoping to pad their majority in the House and beef up their thin leadership hold on the Senate.
A House Democratic campaign committee leader says today's heavy turnout can only help. Democrats are counting on capturing more than 20 GOP seats. Though he cautions that there's been "a tightening in a lot of races" and gains might not be in the "huge numbers" some pundits had envisioned.
As for the Senate, Democrats have fewer seats on the line than Republicans. Of the 35 races on today's ballot, 22 are now held by Republicans, 13 by Democrats. Top prospects include the seats of three retiring GOP senators in Virginia, Colorado and New Mexico.
Democrats are also optimistic that the only two Democratic senators who'll need to give up their Senate seats will be Barack Obama and Joe Biden.
