The Missouri election on Tuesday is capturing national attention as Democratic incumbent Sen. Claire McCaskill faces off against Republican challenger Rep. Todd Akin.
McCaskill is the favorite in the Senate race, but the race just several months ago was considered more competitive. In August, Akin sparked sharp criticism on both sides of the aisle when he said on the idea of getting an abortion in a case pregnancy resulting from rape: "If it's a legitimate rape, the female body has ways to try to shut that whole thing down. But let's assume maybe that didn't work or something. I think there should be some punishment, but the punishment ought to be on the rapist."
The latest polls show McCaskill running ahead of Akin going into Decision Day.
In the presidential contest, Mitt Romney is expected to score an easy win over Barack Obama and capture the state's 10 electoral votes. Missouri Gov. Jay Nixon (D) is expected to secure another term over Republican challenger Dave Spence.
The polls are open between 6 a.m. and 7 a.m. Central time in Missouri on Tuesday.
