Sen. Rand Paul, R-Ky., said Monday that the reason he supports the movement to defund Obamacare is because “It’s the only method at this time to do anything.”

Paul, speaking to Fox News’s Sean Hannity, said he’s doing what his constituents asked him to do, but conceded that victory was not guaranteed.

“People want us to stand up,” Paul said. “I ran on being against Obamacare. [Voters] asked me at every meeting: ‘Stand up and defund it.’ It’s what everybody wants. Now what I will tell them is I may not be able to guarantee victory. But what I can guarantee is I will stand up,” Paul said.

Paul also mentioned that defunding it may not be the ultimate goal for Republicans, but that it was a start.

“But you start out with defunding it in order to maybe get to a delay or maybe to get to where the individual mandate goes away since the employer mandate is already delayed. Why don’t we use our leverage by having the Republican House at the very least get to delaying the individual mandate,” Paul said.
