Romney easily wins Indiana presidential primary
Romney had no serious challenge in the state and easily outpolled Rick Santorum, Newt Gingrich and Ron Paul. Santorum and Gingrich remained on the ballot despite having ended their campaigns.
The former Massachusetts governor will try to return Indiana to the Republican column in November after Barack Obama in 2008 became the first Democrat to carry the state in 44 years.
Romney's only trip to the state this year came Monday night, when he attended a campaign fundraiser in Indianapolis.
Republican Gov. Mitch Daniels endorsed Romney three weeks ago after saying for months he wanted to stay neutral in case Indiana's primary ended up being contested.
