RICHMOND, Va. — At a stop on his book tour Tuesday, Mike Huckabee again defended his decision as Arkansas governor to grant the children of illegal immigrants in-state tuition at state universities.

But he also went a step further, hinting that those children should be put on a path to citizenship — a position more in line with Democrats and DREAMers than some of Huckabee’s more conservative Republican peers who are also weighing bids for the presidency.
