Mitt Romney has the Republican nomination for president all but locked up, adding Indiana and North Carolina to his state tally on Tuesday night with decisive victories. Romney outpaced his only viable challenger remaining, Ron Paul, in both states, winning more than 60 percent of the vote with Paul barely getting over the 10 percent mark. With 74 percent of precincts reporting in Indiana, Romney had a convincing 64 percent of the vote. Rick Santorum, meanwhile was third in both states. Santorum endorsed Romney in an email to supporters Monday night.
