ASTON, Pa. (AP) -- Mitt Romney may be looking to move toward the political center, in the aftermath of a bruising primary fight.
Today, Romney embraced a student loan proposal that President Barack Obama is pushing on the campaign trail. Although House Republicans oppose legislation to temporarily extend low interest rates for student loans, Obama has been calling for an extension.
And, Romney refused to endorse a conservative immigration plan from Florida Sen. Marco Rubio. It would allow young illegal immigrants who've graduated from high school and have no criminal record to get a non-immigrant visa -- but it offers no special path to citizenship.
Romney had said during the South Carolina primary that all illegal immigrants should return to their home country and get in line to be eligible for U.S. citizenship.
Rubio is considered a top potential pick for vice president. The Cuban-American senator is the latest in a string of possible running mates to campaign with Romney. But Romney won't say if Rubio is being considered.
