Republican presidential candidate Mitt Romney has been hitting Michigan hard the few days before Tuesday's presidential primary and now plans to make a stop in Royal Oak on Monday evening.

Romney will bring his “Earn It” bus tour to the Royal Oak Music Theatre from 6:15-7:30 p.m. His campaign website also promises Romney will have a "special musical guest from Detroit."  

The Michigan native and former Massachusetts governor starts the day with an 8:45 a.m. rally in Rockford and then in Albion at 1 p.m. for a rally.

Romney and fellow GOP hopeful Rick Santorum appeared at a conservative rally Saturday in Troy.

Santorum is scheduled to attend the Livonia/Farmington Area Chamber of Commerce Breakfast this morning in Livonia before taking his campaign bus to Lansing and Kalamazoo.

Candidate Ron Paul plans a Monday afternoon rally with Michigan State University students and an evening rally with doctors in Dearborn.
