NBC/Marist: empate en Michigan; cómoda ventaja de Romney en Arizona

NBC News:

Less than a week before Tuesday’s crucial Republican presidential primary in Michigan, a new NBC News/Marist poll shows Mitt Romney and Rick Santorum locked in a statistical tie, while a separate NBC/Marist survey shows Romney comfortably leading in Arizona, which holds its primary the same day.

In Michigan – which has turned into a make-or-break contest for Romney – the former Massachusetts governor gets the support of 37 percent of likely GOP primary voters, including those who are leaning toward a particular candidate.

Santorum, the former Pennsylvania senator, gets 35 percent, and he’s followed by Texas Rep. Ron Paul at 13 percent and former House Speaker Newt Gingrich at 8 percent.

“Michigan is neck and neck,” says pollster Lee Miringoff, director of the Marist College Institute for Public Opinion, which conducted both surveys.

But in Arizona, Romney is on safer ground: He receives the support of 43 percent of likely GOP primary voters, Santorum gets 27 percent, Gingrich 16 percent and Paul 11 percent.
