BOSTON – Republican presidential candidate Mitt Romney is drawing a disproportionately high amount of campaign funds from people who have given him the legal maximum, weakening his ability to raise money from such proven donors as the GOP nomination fight drags on.
Far more than his three rivals, Romney has tapped these large donors to build his campaign fund. To date, about two-thirds of his money has come from donors who have given him $2,500, the legal limit for a primary campaign, according to the Campaign Finance Institute, a nonpartisan research organization.
By contrast, about 18 percent of Rick Santorum’s money has come from those who have maxed out. For Newt Gingrich, the comparable figure is 16 percent; for Rep. Ron Paul, 11 percent.
