Former House Speaker Newt Gingrich's American Solutions PAC raised $314,106 over the past month and a half, while directing more than $200K to other Republican candidates across the country. 

Gingrich also donated a total of $20K to Iowa's House Majority Fund, according to the committee's filing with the Federal Election Commission.

The number makes Gingrich's federal PAC haul second only to former Alaska Gov. Sarah Palin, whose committee took in more than $460K over the same period and reported $1.2 million cash on hand. 

The former House Speaker also has a 527 group through which he has done the bulk of his fundraising during the past year.  

Palin's PAC gave money to close to 50 Republican congressional candidates in the month leading up to the midterm elections. She also donated to state Republican Parties in South Carolina, New Hampshire and Alaska. 

Former Massachusetts Gov. Mitt Romney's Free and Strong America PAC raised $285,295 between Oct. 14 and Nov. 22, but raised an additional $273K through his network of state PACs. That pushes Romney's total haul to more than half a million dollars. His federal PAC reported more than $1 million cash on hand. 

Minnesota Gov. Tim Pawlenty's PAC raised less than $140,000 over the same period, while Mississippi Gov. Haley Barbour's committee raised $108,152. 

Barbour doled out more than $62,000 to other GOP campaigns and state parties across the country. He gave $5,000 to the state Republican Party in both Iowa and New Hampshire. He also donated to more state parties than any other contenders, including the state Republican Parties in Michigan, Wisconsin, Pennsylvania, Colorado and Minnesota.
