Right to Rise, the super-PAC supporting Jeb Bush’s presidential campaign, reported on Sunday raising $15.1 million in the second half of 2015.

Almost two-thirds of the committee's second-half funds came from a single contribution. A company owned by Hank Greenberg -- former head of American Insurance Group -- gave $10 million in October.

The super-PAC raised a total of $118 million on behalf of the former Florida governor in 2015, and dominated the presidential field in terms of spending by burning through almost $60 million in one year.

In the fourth quarter of the year alone, the committee spent over $54 million to promote Bush, who has a RealClearPolitics polling average of 4.8 percent nationally.
