Republican talk about an electric border fence, e-verify and deportation was one thing in Iowa, New Hampshire and South Carolina. Tomorrow in Florida and Saturday in Nevada it will be a different story, when many voters will be Hispanics. Obama won 58 percent of Hispanics in 2008, but many are having second thoughts, especially because of the economy. What other issues concern them most? Are Mitt Romney and Newt Gingrich hitting the right buttons? Can Republicans reconcile their appeals to Tea Partiers and the fastest growing bloc of American voters?
