Rasmussen: Romney, en cabeza en Michigan y Arizona

En Michigan:

True to a primary season already marked by sudden and surprising ups and downs, Mitt Romney has jumped back into the lead in Michigan’s Republican Primary race. The vote’s on Tuesday.

The latest Rasmussen Reports telephone survey of Likely Republican Primary Voters in Michigan shows Romney with 40% of the vote and former U.S. Senator Rick Santorum with 34%. The poll was conducted on Thursday night, following the last scheduled debate among the GOP candidates.

En Arizona:

Former Massachusetts Governor Mitt Romney has widened his lead over leading challenger Rick Santorum in the Arizona Republican Primary race with the vote just four days away.

The latest Rasmussen Reports telephone survey of Likely Arizona Republican Primary Voters finds Romney leading Santorum 42% to 29%. The survey, taken after the last scheduled debate of the GOP candidates, finds Romney up three points and Santorum down two from a week ago when it was a 39% to 31% race.

Former House Speaker Newt Gingrich earns 16% support, and Texas Congressman Ron Paul trails with eight percent (8%), marking virtually no change for either man from the previous survey. Only one percent (1%) favors another candidate in the race, and three percent (3%) remain undecided.
