Trump's net favorability jumped 16 percentage points in the last two weeks, according to a Gallup survey released Friday. Trump went from a 16 percent net positive rating in mid-August to 32 in the latest tally.

"This marks a significant shift; Trump's image previous to the last two weeks had been relatively stable despite the extraordinary media attention his candidacy has engendered," said Gallup in a release announcing the results.

GOP rivals Carly Fiorina and Ben Carson also saw gains in net favorability over that time, with gains of 5 and 3 points, respectively.

But a number of candidates have seen their image slide over that time, led by Ohio Gov. John Kasich, who slipped 12 points from a net favorability of 27 to 15, the biggest drop.

Bush and Wisconsin Gov. Scott Walker also saw their favorability go down.

Bush had a net favorability of 25 two weeks ago and is now at 19, while Walker went from 37 to 31, each down 6.

New Jersey Gov. Chris Christie was down 4 points. Sen. Marco Rubio (Fla.) remained steady, going up 1 point. Former Arkansas Mike Huckabee and Sen. Rand Paul each seeing a 2 point bump.

The survey is based on Gallup's daily tracking across two-week periods from Aug 5-18 and Aug 19-Sept. 1. Gallup surveyed 1,000 GOP and GOP-leaning independents with a 4-point margin of error.
