LANSING, Mich. — Republican presidential candidate Mitt Romney plans to make a campaign swing through Michigan.

A campaign spokesman said Tuesday the ex-Massachusetts governor would attend a Grand Rapids fundraiser Tuesday night and another in Detroit on Wednesday.

On Thursday, Romney is to campaign at a Livonia diner and attend a business round table in Detroit. They're his first Michigan stops since formally entering the race last week.

Also Tuesday, the Romney campaign named Rob Macomber as state director, along with several other Michigan staff members.

Michigan could be a key state in Romney's second attempt to win the GOP nomination.

He won the state's 2008 primary, building in part on warm memories of his father George Romney's time as governor. Mitt Romney quit the race after John McCain beat him in Florida.
