The Kentucky Senate passed a resolution Tuesday calling for a constitutional convention on a balanced federal budget amendment. The vote was strictly along party lines, with one exception.If Congress refuses to act on a constitutional amendment favored by the states, the states can force a constitutional convention. It’s never happened before, but U.S. Senator Rand Paul says it’s time, because Congress refuses to approve a balanced budget amendment.“If we do nothing with spending, within a decade entitlements and interest occupy the whole budget. Think about that. The whole budget! No money for defense. No money for roads. No money for education. No money for anything if we don’t reform the system," he says.After listening to Senator Paul’s comments on the Senate floor, 22 Republicans joined the call for a constitutional convention. But Republican Senator Julie Denton joined the chamber’s 15 Democrats in opposing the resolution.“I do have some concerns, as to what this could mutate into," she said. "Congress now has the ability to limit its spending and it has chosen not to and I do have concerns about where this would go. It’s going to pass anyway, but I doubt that it’ll pass in the House. So I don’t know that it much matters, but I vote no."Two-thirds of the states pass similar resolutions to force congress to act. To date, at least 22 states have done so, but each state's resolution is worded differently.
