A conservative super PAC launched a new TV ad Tuesday hitting Senate Minority Leader Mitch McConnell (R-Ky.) for the compromise bill he helped craft to reopen the federal government and raise the debt ceiling.

"Conservatives asked Mitch McConnell to lead the fight against Obamacare. He didn't listen," says the narrator of the ad Senate Conservatives Action released. "Instead, McConnell helped Barack Obama and Harry Reid fund Obamacare."

The group cites McConnell's vote earlier this month for a bipartisan compromise that ended the government shutdown and raised the nation's borrowing authority, and his vote to end debate on a stopgap spending bill in September. Some conservatives were dissatisfied with the final compromise bill because it made no major changes to the health-care law known as "Obamacare."

The group is spending $330,000 to air the ad.

Senate Conservatives Action is an arm of Senate Conservatives Fund, which recently endorsed Louisville businessman Matt Bevin, McConnell's GOP primary opponent.

"When Mitch McConnell was rallying conservatives to fight Obamacare the fundraising group responsible for these ads was working day and night to ensure Barack Obama's majority in the Senate," responded McConnell campaign spokeswoman Allison Moore. "You get an idea of what team the Senate Conservatives Fund is on when you realize that there are scores of Democrats who actually voted for Obamacare up for re-election and this group, purporting to support conservative causes, is investing their well-intentioned donors money into attacking the man responsible for leading the opposition to the law."
