(CNN) - Fifty percent of adults say they would support government funding for all federal campaigns while banning private contributions, according to a national survey released Monday.
The Gallup poll showed 44% would oppose such a move, while 6% weren't sure. More Democrats (60%) than Republicans (41%) said they supported public financing.
Last year's political races was the most expensive on record; in total, candidates, parties and outside groups spent $7 billion during the 2012 election cycle, a record breaking – though not surprising – figure for campaign expenditures, according to the Federal Election Commission.
The agency said they expected those numbers to continue rising in coming years. Aside from the unlimited amounts that super PACs can raise, contributions to campaigns themselves are poised to spike. The FEC increased the limits on contributions to campaigns to $2,600 per election to keep up with inflation. The annual limit for individual contributions to party committees increased to $32,400.
The Gallup poll was conducted by telephone June 15-16 from 1,015 adults nationwide. The sampling error was plus or minus 3 percentage points.
