Ron Paul endorses McCain's primary challenger

Former Texas Congressman and two-time Republican presidential hopeful Ron Paul endorsed the Republican primary challenger to Arizona Sen. John McCain on Monday, citing her “dedication to smaller government and restoring more of our personal liberties.”

“As a physician, you have seen firsthand how ObamaCare has reduced our liberties in just a few short years,” Paul wrote in a letter to McCain’s challenger, former state legislator Dr. Kelli Ward. “During your time as state senator, you have fought to reduce the size of government and restore the liberties of Arizonans. We need to elect more people into the U.S. Senate to stand alongside my son, Rand Paul.”
