PHILADELPHIA (CBS) - Likely Republican candidate for president Mitt Romney is in Philadelphia today at the Universal Bluford Charter School in Philadelphia for a round-table discussion and a tour of classrooms.

Romney briefly talked education yesterday, continuing to use the playbook that has him heaping blame on the Obama administration without saying much about what he’d do differently.

He did, yesterday, offer some vague details, including a voucher-like plan that would allow low-income and disabled students use federal money to attend public schools, public charter schools, private schools, or tutoring and digital courses.

Romney attacked President Obama saying he’s too close to teachers’ unions — which he argues is a group that’s lost its way.

Obama’s campaign countered attacking Romney’s time as governor, with policies they say resulted in the loss of 14,000 education jobs and larger class sizes.
