The Republican is seeking a second term in Congress, and faces Democratic challenger, Dave Crooks.
Both have spent the past few days making their final arguments to voters.
Crooks claims Bucshon voted to end the Medicare guarantee, and that Bucshon's vote would cost seniors an extra $6,400 a year.
"If you are 55 years of age and younger," said Crooks, "the Congressinoal budget office, non-partisan group, has made it very clear, along with AARP and other people who are watching this debate closely. They believe that privatizing Medicare and not keeping the Medicare guarantee will definetly cost seniors a lot of money."
"They're lies," said Bucshon. "The fact of the matter is the stuff my opponent has been saying about my record on Medicare is not true. In fact in 2011 Politicact.com, a national non-partican
fact checking agency called it the lie of the year, what they're saying about me on Medicare."
