TAKING IT TO THE NEXT LEVEL: Exclusive: Jim DeMint joins growing ‘convention of the states’ movement. “Former South Carolina senator Jim DeMint, ousted last month as head of the Heritage Foundation think tank, is joining a fast-growing, conservative movement that is pushing states to seek a constitutional convention to rein in federal spending and power. DeMint, a prominent figure among the Tea Party activists who helped Republicans seize control of the U.S. House of Representatives in 2010, will serve as a senior adviser to the Convention of the States Project, providing a jolt to its efforts to marshal grassroots support for a state-led movement to amend the U.S. Constitution.”
