Arizona Sen. John McCain still leads by more than 10 points in his competitive primary race against former Rep. J.D. Hayworth, a new Rasmussen poll finds (June 16, 707 LV, MoE +/- 4%). But he dropped back below 50%, a sign of vulnerability for the four-term senator and former presidential nominee. The entrance of Tea Party activist Jim Deakin brought both McCain and Hayworth down from last month.

McCain 47 (-5 vs. last poll, May 19)
Hayworth 36 (-4)
Deakin 7
Und 8

The Aug. 24 primary is now just two months away. At this point, RCP rates the general election race Likely Republican.
