WASHINGTON, DC - MARCH 13:  Sen. Rand Paul (R-KY) speaks during a news conference with Sen. Mike Lee (R-UT) (L) and Sen. Ted Cruz (R-TX) to announce a plan to defund the Patient Protection and Affordable Care Act, also known as Obamacare, at the U.S. Capitol March 13, 2013 in Washington, DC. Although the conservative senators sponsoring the legislation expect it to fail, they believe it is an important survey of who supports health care reform.  (Photo by Chip Somodevilla/Getty Images)
