Supporters of Sen. Ted Cruz (R-Tex.) have launched an online petition to draft him into the 2016 presidential race, and a Cruz staffer is leaving the senator's office to help out.

The Web site, RunTedRun.com, is seeking to get 1 million signatures in hopes of luring Cruz to run for president.

The effort is spearheaded by a super PAC that was set up in January called "Draft Ted Cruz for President." The super PAC is based in Houston and, until Wednesday, little was known about it.

But Cruz regional director Raz Shafer announced Wednesday on RedState.com that he is leaving the senator's office to run the PAC, lending credibility to the effort.

As of early Wednesday afternoon, the effort had 232 signatures.
