Among those registered voters who said they plan to participate in the Republican primary, former Florida Gov. Jeb Bush has fallen to third place, and Sen. Marco Rubio to fourth. Retired neurosurgeon Ben Carson has leapfrogged to second, just 4 points behind real-estate developer Trump.

A similar survey also for the T-U released Aug. 7 showed Carson third. Now he’s tripled his support in the Sunshine State while Bush has fallen to third and lost 7 points.

In the meantime, Trump has added 2 points, and in the shuffle widened his lead over second from 1 point to 4.

Rubio hasn’t budged in fourth place. Former Hewlett-Packard CEO Carly Fiorina has risen to fifth place by building her 1 percent then up to 5 percent now.
