Yes it's basically a credit. I think all non-business deductions should go away and turn them into fixed credits (vanishing most of them entirely). Right now two homeowners each with $1000 in deductible mortgage interest, have different tax liability reductions if they're at different tax brackets. The one in the higher bracket actually ends up with a greater reduction in tax for the same deduction. And so on.
