Rudy Giuliani may need to be looking over his shoulder at Mike Huckabee if the former New York City mayor is still counting on overcoming the possibility of early state losses by winning the big states later. Riding a huge surge of conservative support, Huckabee has gained 6 points in the last two weeks and now trails Giuliani by only 29 percent to 24% percent, just slightly above the poll’s 4.8 margin of error. Mitt Romney polls at 20 percent and everyone else is in single digits.

Giuliani’s lead in California – once 21 points – is now down to 8 points. He leads the pack with 28 percent, but Huckabee has gone from 8 percent six weeks ago to 20 percent today. There is a virtual three way tie for third with Romney at 16 percent, John McCain at 14 percent and Fred Thompson at 13 percent. The margin of error is 4.5 percent.

On the Democratic side, Hillary Clinton leads Barack Obama 49 percent to 30 percent, narrowing a 37 point margin favoring Clinton two months ago. John Edwards is at 14 percent with all other candidates in single digits. The biggest factor in the swing toward Obama has been the movement of male voters towards his fold that last fall had favored Clinton.
