Michigan to remain GOP presidential ground zero | News

GRAND RAPIDS (WZZM) - Republican presidential candidate Rick Santorum has expanded his campaigning in conservative west Michigan, adding stops in Muskegon and Holland Monday, hoping to capitalize on his surging poll support.   In a "poll of polls" by realclearpolitics.com, Santorum has 37% support in Michigan to Romney's 30%.  Newt Gingrich and Ron Paul each had 10% support.

Romney has long been the candidate of the "establishment" republican party, while Santorum has appealed of late more to the tea party and conservative wings.   Santorum Monday night will wade deep into the heart of that establishment when he speaks to the Kent County Republicans' Lincoln Day dinner in Grand Rapids.   His speech will follow a pitch for Romney made by a surrogate, Virginia Governor Bob McDonnell.

Romney himself will campaign in eastern Michigan Tuesday.

Santorum will appear Monday afternoon at the Holiday Inn in Muskegon at 3 PM.   It's located at 939 3rd Street.   At 5 PM, Santorum will speak at Hope College's Maas Auditorium.
