JEFFERSON CITY, Mo. (AP) -- Democratic Sen. Claire McCaskill and Republican challenger Todd Akin are rallying supporters and encouraging volunteers as they make a final push toward Election Day.At a revival-style rally Saturday in Kansas City, Akin told about 150 supporters that he's sensing a lot of energy for his campaign. Participants were encouraged to grab a stack voting guides and distribute them at Sunday church services. Akin also was holding rallies Saturday in Jefferson City and St. Louis County.McCaskill traveled to Columbia to encourage volunteers who were setting out to knock on more than 3,500 doors. The canvassers were targeting Democrats who voted sporadically in the past to make sure they would get to the polls Tuesday and -- if necessary -- to persuade them to vote for McCaskill.
