Washington (CNN) - The amount of money in a voter's bank account may influence for whom they cast their vote in 2012, according to a new national survey.
A Gallup Poll released Monday indicates higher income earners supporting Republican former Massachusetts Gov. Mitt Romney over former Alaska Gov. Sarah Palin for the Republican presidential nomination.
Romney's support climbed to 21 percent among those earning $90,000 or more compared with 9 percent support among those making less than $24,000 annually.
The opposite was true for Palin who received support from 7 percent of likely Republican voters making over $90,000 and 22 percent for those making less than $24,000 annually.
The Romney-Palin disparity continued among education levels. Republicans with a college degree were more likely than those without a degree to support Romney, 21 percent to 13 percent. However, nearly twice as many Republicans without a college degree supported Palin, 16 percent to 9 percent.
Romney formed a presidential exploratory committee in April and Palin, who has not ruled out a bid, has also not taken any concrete presidential steps.
Other potential 2012 candidates including former Arkansas Gov. Mike Huckabee, former House Speaker Newt Gingrich and Texas Rep. Ron Paul did not spark strong socioeconomic differences among Republican voters. Minnesota Rep. Michele Bachmann, Indiana Gov. Mitch Daniels and former Minnesota Gov. Tim Pawlenty, who are all weighing a bid for the White House, registered in the low single digits.
The poll surveyed 3,304 Republican or Republican-leaning independents in the United States across three national Gallup surveys conducted in February, March and April with a sampling error of plus or minus two percentage points.
