(CNN) – Mississippi Gov. Haley Barbour, who declined a 2012 run for the White House in April, will throw his weight behind the effort to unseat President Obama by joining fundraising powerhouse American Crossroads and Crossroads GPS.
The groups, helmed by GOP strategist Karl Rove, announced Barbour’s addition Thursday, on the heels of President Obama’s address to a joint session of Congress on jobs.

With new support from the former chair of both the Republican National Committee and the Republican Governor’s Association, American Crossroads and Crossroads GPS announced they would “more than double” the combined fundraising goal for both groups by the end of 2012, up from the original $120 million mark.
Aiming to reach $20 million in fundraising for 2011, the group saw their goal exceeded with a haul of $24.5 million to date.
“We are reaching high in our fundraising goals because we believe this is going to be a destiny-shaping election for our country,” said Steven Law, who serves as president of both groups.
Crossroads GPS is a conservative-leaning advocacy organization. American Crossroads is an independent 527 group that serves as a fundraising arm with the ability to accept contributions without limits or restrictions.
Barbour will serve the groups in a volunteer capacity as they fundraise through 2012.
