(CNN) - A day after West Virginia Gov. Joe Manchin released an ad calling his opponent's ideas 'crazy,' Republican John Raese launched his own ad blasting Manchin and "his friend President Obama."
"You've heard me say that I won't be a rubber stamp for Barack Obama," Raese says in the ad. "In the Senate, I'll fight to repeal 'Obamacare,' stop its tax increases, and protect our seniors."
Though both Manchin and Raese have been critical of the president throughout the campaign - Manchin literally shot a bullet through a copy of the Democratic-favored Cap and Trade bill in a recent ad - Raese has consistently sought to tie the Democratic governor to Obama, who is extremely unpopular in West Virginia.
Manchin meanwhile has repeatedly said that Raese, a wealthy businessman, is out of touch with West Virginians.
In his latest ad, Manchin calls Raese's policy ideas "crazy" and "bad for West Virginia," – a charge Raese's campaign was quick to rebuff.
"Joe Manchin believes that those who are committed to cutting spending and a strong National Defense are crazy," said Raese campaign spokesman Kevin McLaughin. "No Joe, supporting 'Obamacare' is crazy. Wasting one trillion dollars on a failed stimulus is crazy. $13 trillion in national debt is crazy. Cap and trade legislation is crazy."
Recent polls show that Raese and Manchin remain in a tight battle in their race to replace the late Sen. Robert Byrd, who died earlier this year.
