Poll: McCain up 15 vs. Hayworth

From NBC's Mark Murray
A new Research 2000/Daily Kos poll shows Arizona Sen. John McCain with a comfortable 15-point lead over GOP primary challenger J.D. Hayworth, 52%-37%.

Interestingly, both men are viewed favorably among Arizona Republicans. McCain's fav/unfav with them is 76%-19%, and Hayworth's is 61%-16%.

What's also clear is that Arizona still isn't Obama country. The president's overall fav/unfav in the state is 41%-55%, according to the poll. And 44% of Arizonans say they would be more likely to vote for a candidate who wants to repeal the new health care, versus 39% who say they would be more likely to vote for a candidate who supports the law and improving it.
