COLUMBIA -- Wednesday is the last day to register to vote in Missouri if you want to cast your ballot in November.

Obama supporters took full advantage of that Tuesday in a last ditch effort to recruit new voters. At Stephens College, College Democrats went from table to table in their campus cafeteria encouraging other students to register.

"Missouri, as I think everyone knows, is a big swing state this year," said Polly Edelstein, one of several Stephens College Democrats trying to recruit new voters. "It really could be the college vote that decides who wins this election. So we just want to get everyone registered and have the ability to vote."

Edelstein said they registered seven new voters Tuesday and more than 180 since September.

Lincoln University, along with the University of Missouri, Columbia College and Truman State also held "Youth Vote Days of Action," - part of the Obama campaign's "all-out effort to register Missouri voters in every corner of the state."

In recent weeks, county election offices across the state have been working hard to process the large number of new voter registrations. This year there are 233,000 new voters in Missouri who have registered for the first time.

Statewide, there are more than 4 million registered voters. In Boone County, there are more than 109,000 who are already registered. In Callaway County there are nearly 30,000 registered voters. And in Cole County, more than 52,000 people are registered to vote.
