“Conservatives asked Mitch McConnell to lead the fight against Obamacare. He didn’t listen,” the 30-second ad says. “Instead, McConnell helped Barack Obama and Harry Reid fund Obamacare. Now Kentucky families are paying the price. Premiums up, lost coverage, even lost jobs. When Kentucky needed Mitch McConnell the most, he let us down. Now he’s asking us to give him six more years in Washington?”

The conservative group has endorsed McConnell’s GOP primary opponent,

, Louisville businessman Matt Bevin. SCF spent $330,000 on the ad, which will air on broadcast and cable beginning Wednesday and running through Nov. 12.

The spot is the second the SCF has run this fall. In September, the group ran ads urging McConnell to defund the president’s health care law — a battle that ultimately led to the government shutdown.

The winner of the GOP primary will face Kentucky Secretary of State Alison Lundergan Grimes, the likely Democratic nominee,  in 2014.

The Kentucky Senate race is rated a Republican Favored contest by Rothenberg Political Report/Roll Call.

“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,” Moore said in a statement. ” 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.”
