Romney and Santorum Tied in US Polls

Mitt Romney and Rick Santorum

Mitt Romney and Rick Santorum go head to head as polls open in the States of Michigan and Arizona to choose the Republican presidential candidate. Both candidates have been campaigning intensively for the past few days.

The latest opinion polls suggest that Romney has a marginal lead in Michigan. Newt Gingrich and Ron Paul are also candidates in both states. Political analysts believe that a victory in his home state of Michigan is key for Romney.

The winner of the eventual nomination will face the United States President Barack Obama in the upcoming November elections. (AV)
