The event comes as Romney is ratcheting up his criticism of former senator Rick Santorum’s (R-Pa.) record in Washington. It also comes as Romney is looking to head off a win in his home state by his primary rival for the GOP nod.
Santorum, who made a three-stop swing through western Michigan on Monday, is headed to Arizona today, where he’ll address the Maricopa County Lincoln Day Luncheon in the afternoon.
Expected to be in attendance is Joe Arpaio, the embattled Maricopa County sheriff who had endorsed Texas Gov. Rick Perry (R) before Perry dropped out of the race. It will be worth watching whether Arpaio, who is known for his strong anti-illegal immigration stance, makes any new endorsements this time around.
Rep. Ron Paul (R-Texas) takes a day off the trail today, and former House speaker Newt Gingrich (R-Ga.) is spending a second day in a row in Oklahoma.
