Obama and Romney Super PACs Get Best Month in SeptemberSuper PAC supporting President Barack Obama got its best month in September by raising $15.2 million. A group supporting Republican candidate Mitt Romney collected $14.8 million. According to officials of Priorities USA Action, a pro-Obama group, Chicago Mayor Rahm Emanuel helped with the fundraising of the group.

Bill Burton, a former Obama aide who helps supervise the group, said in an email that Democrats know that the race is closer than they previously thought it was and if they want to win in November, everybody must be involved. In August, Priorities USA Action got $10.1 million.

The pro-Romney super PAC Restore Our Future got donations from Houston Texans owner Bob McNair, who donated $1 million, and Texas home builder Bob Perry, who gave $2 million. Perry has already donated a total $9 million to the super PAC, which is run by former Romney aides.

Super PACs can collect unlimited corporate and union money but they are not allowed to coordinate their advertising with candidates. Restore Our Future planned to use $12 million for ads in nine key states next week. It hopes that it can help Romney sprint towards Election Day.

The House Majority PAC, another Democratic group, also got its best fundraising month in September. It collected $5.9 million. Spokesman Andy Stone said that the group is on track to double the amount in October. The group’s goal is to elect Democrats to the House.

Democratic groups haven’t filed reports to indicate the sources of their funds. According to Houston trial lawyer Steve Mostyn, he gave $1 million to Priorities USA Action. His total donation is $3 million.

Wealthy supporters have dominated the donations to super PAC backing Democrats and Republicans alike. Oxbow Carbon, a mining and petroleum company run by Republican supporter Bill Koch, gave $1 million to Restore Our Future in September. The company gave $2 million to the super PAC.
