The fight for registration may be over, but the battle for participation is just beginning. The weapon of choice for both parties? The phone.

"We just have a few short days until November 4th," Obama volunteer James Marshall Jr. said.

Volunteers at the Obama Campaign office in Lansing are combing through their phone lists and making sure everyone heads to the polls on election day.

"My focus is the phone banking and talking to people who haven't made up their minds yet," Marshall said.

And even though the McCain campaign announced it wouldn't target Michigan anymore, volunteers at the Ingham County Republican Party headquarters are still dialing digits.

"Even since the announcement, we've closed the gap," Chair of the Ingham County Republican Party Norm Shinkle said.

And they're focusing on absentee voters.

"We're making sure everyone who can't be in town and needs an absentee ballot, gets one," Shinkle said.

Just days after Obama rallied at MSU's campus, volunteers are making sure the thousands of college students who registered, actually vote too.

"I think the registration forms and ballots can be confusing and intimidating for new voters, but we want to make it as easy as possible for them," Obama Volunteer Jeffrey Omura said.

Voting is a right both campaigns want you to exercise November fourth.
