The latest Fox News national poll finds another reshuffling in the race for the 2016 Republican nomination, as Wisconsin Gov. Scott Walker gets a post-announcement bump and businessman Donald Trump claims more of the spotlight.

Former Secretary of State Hillary Clinton still dominates the Democratic race. Yet the poll also warns trouble may be ahead for her.

Among Republican primary voters, Trump captures 18 percent. He’s closely followed by Walker at 15 percent and former Florida Gov. Jeb Bush at 14 percent. No one else reaches double-digits.

Support for Trump is up seven percentage points since last month and up 14 points since May. He’s also the candidate GOP primary voters say they are most interested in learning more about during the debates.
