In a fight with few political winners, one clear beneficiary of the budget impasse on Capitol Hill has been Sen. Ted Cruz, who Tuesday posted a fundraising haul of roughly $1.19 million for the past three months.

The campaign contributions to Cruz, a leader of conservative Republicans' fight to defund Obamacare as part of a broader spending agreement, would be notable under any circumstances — but even more so because Cruz, R-Texas, will not run for re-election until 2018. He is widely rumored to be considering a bid for the presidency in 2016.

From July through the end of September, Cruz's leadership PAC brought in roughly $800,000. Of that, about $300,000 came from small donors giving less than $200 each, indicating a swell of grassroots support behind Cruz and his cause. Cruz's re-election committee brought in an additional $390,000, his campaign said.

Much of the cash flowed in after Cruz staged a dramatic 21-hour speech on the Senate floor to protest funding for the Affordable Care Act. Although Cruz rankled many of his Republican colleagues with his vocal obstructionism, he won the support of myriad conservative outside groups, who urged their supporters to contribute to him.
