When former Florida Gov. Jeb Bush got to work on his new book on immigration, he was expected to be out in front of his party urging a broader conversation with Hispanics and more open legislation. After all, he had previously supported a pathway to citizenship for immigrants here illegally. Instead, it's fellow Florida Republican Marco Rubio in the lead, and Bush who's explaining an apparent reversal on the issue of citizenship. Both are likely candidates for president in 2016.
