Three new California polls with field dates ending Saturday, February 2nd were released today — all showing growing momentum for Mitt Romney, despite endorsements this past week for John McCain by Rudy Giuliani and Governor Arnold Schwarzenegger.

All three polls show statistical dead-heats between Romney and McCain:

American Research Group (Feburary 1-2, 600 LV)
Romney = 33%
McCain = 32%
Huckabee = 16%
Paul = 8%
Other / undecided = 11%

Rasmussen (February 2, 693 LV)
Romney = 38%
McCain = 38%
Huckabee = 10%
Paul = 6%
Other / undecided = 8%

* Note: Rasmussen had previously found McCain leading Romney by 7 points in mid-January and by 4 points earlier this week.

Reuters / C-SPAN / Zogby (January 31—February 2, 1,185 LV)
Romney = 37%
McCain = 34%
Huckabee = 12%
Paul = 5%
Other / undecided = 13%

With McCain pulling in significant double-digit leads in Northeastern states like New Jersey, Connecticut, and New York, California becomes an important race for Romney, not so much from a delegate perspective but from a media perspective. A victory over McCain in the largest state in the nation is about the only political event that could derail the momentum and positive media coverage McCain has enjoyed during the past few weeks.
