To nobody’s surprise, Mitt Romney has won the Arizona Republican Primary:

Mitt Romney will win Tuesday’s Arizona primary, CNN projected based on exit polls, and he took an early lead over rival Rick Santorum in Michigan, a key contest in the Republican race for a candidate to run against President Barack Obama in November.

The victory in Arizona, where exit polls showed Romney getting 43% to 28% for Santorum, gives the former Massachusetts governor all of the state’s 29 delegates in the winner-takes-all primary. Trailing well back were the other two GOP contenders — Newt Gingrich and Texas Rep. Ron Paul.

Given the polls we’ve seen over the past week or so, this isn’t a surprise. Nonetheless, it’s a solid 29 delegates in Mitt Romney’s column. Michigan remains up in the air this hour, but Romney is leading so far, which may bode well for him.
