Trump Dominates GOP Presidential Primary Polls with Widening Lead.

Former President Donald Trump has a 30-point lead over his closest potential challenger, Florida Gov. Ron DeSantis, among Republican primary voters, according to a new Fox News poll. Trump's margin is double the 15-point lead he had in last month's poll. Former Vice President Mike Pence came in third with 6 percent, while former Rep. Liz Cheney and former Ambassador to the United Nations Nikki Haley tied with 3 percent each. Trump and Haley have officially launched their bids for the White House, while most of the others included in the poll have not but are rumored to be possible candidates. The latest poll comes as Trump could potentially be charged in a Manhattan investigation into a hush money payment that was made to adult film star Stormy Daniels ahead of the 2016 presidential election.
