WASHINGTON (AP) — Republican John McCain is making promises that would cost billions of taxpayer dollars, yet he is vague about how he would pay for them.

McCain is handing around a campaign grab bag of goodies. There are little treats like a summer gas-tax holiday and new mortgages for struggling homeowners, and there are big plums like tax breaks for corporations and families with children.

Unlike the Democrats, McCain has made a career of trying to cut spending. He rails against spending in nearly every speech.
