Washington (CNN)Donald Trump's feud with Jeb Bush just got more interesting as the billionaire businessman is now leading the former governor in his own state of Florida, a general election battleground that carries increasing importance in the GOP primary race, according to a new poll.
Trump is leading the GOP presidential primary race in Florida with 21% of support compared to Bush's 17%, according to a Quinnipiac University poll released Thursday. Florida Sen.
