A record number of Americans are expected to head to the polls tomorrow.
One of the biggest concerns is health care.
Here's a breakdown of where each presidential candidate stands.
Meet Andry Sweet and Joline Krolicki, two women with two very different political views. Andry is voting for Obama, and Joline is voting for McCain.
Joline is a retired teacher who now works at a Methodist church. She says McCain will allow her to pick her own health coverage.
Andry works for a non-profit organization. She likes that Obama's plan will help more Americans get health insurance.
Under McCain’s plan, individuals will get a yearly tax credit of $2500, $5000 for families, to put toward the health plan they choose.
Obama will allow uninsured people to buy coverage at lower costs from private insurers or from a government-run, national health plan.
"I think at this point, it's the only thing that's really going to get costs under control,” Andry says.
"I do not want to rely on the government for supplying me with things that I am perfectly capable of choosing on my own," says Joline.
McCain won't require anyone to buy insurance.
Obama will require all children to be insured.
McCain will put a tax on the funds employers contribute to health insurance.
Obama will require employers to offer health coverage or contribute to a government-run program.
Both candidates will allow Americans to buy drugs from foreign countries.
Health care is a concern that won't go away.
"It's a huge issue," says Andry.
"It's on the minds of so many people," Joline says.
For Andry, Joline and many Americans, it's an issue that tops their list this election.
The Obama campaign estimates his health care plan will cost about $1.6 trillion over 10 years, or $50 billion a year.
The McCain campaign doesn't provide an estimate, but according to one analysis, his plan would cost about $1.3 trillion over 10 years.
