Presumptive Republican Vice Presidential nominee Paul Ryan previewed his convention speech Monday during a send-off rally at his hometown high school in Janesville, Wis., saying he and Mitt Romney “are going to honor the fact that this country was created on an idea by our founders: Our rights come from nature and God, and not from government.”

Ryan drew a big-picture contrast between the Republican ticket’s vision of a more prosperous country and President Obama’s America, which he described as “a nation in debt, a nation in doubt, a nation in decline.”
