The organizers behind American Crossroads, one of the wealthiest and most influential conservative political action groups, are launching a new super-PAC aimed at helping Republican primary voters select viable general-election candidates.

The group, called the "Conservative Victory Project," will be led by American Crossroads President Steven Law and advised by former George W. Bush aide Karl Rove. It is intended as a response to a 2012 electoral cycle that saw Tea Party candidates like former Rep. Todd Akin in Missouri and Richard Mourdock in Indiana lose Senate races where Republicans were thought to have an advantage.

"Our party has lost at least six Senate races in the last two election cycles not because of conservative ideas but because of undisciplined candidates and subpar campaigns," Victory Project spokesman Jonathan Collegio told CNN.

"We want to elect conservative candidates to the House and Senate," he added. "But we have to win general elections."

The decision to found the Victory Project comes after a particularly brutal election cycle for Rove-backed candidates. Crossroads spent some $127 million in support of Mitt Romney's unsuccessful presidential bid. Moreover, 10 of the 12 Senate candidates and four of the nine House candidates backed by Rove were also defeated by their Democratic counterparts.

The group's founding drew immediate fire from some Tea Party groups, who have sought to pull the Republican Party to the right through primary challenges of establishment figures.

"TPPatriots want to save USA. Karl Rove wants to line pockets-Don't Tread on Us! Tea Party bites back-never gives up!," tweeted Tea Party Patriots executive Jenny Beth Martin over the weekend.
