The leading Republican presidential candidate in donor and establishment support is down to just four percent of the vote in a new national poll. Jeb Bush, the former Florida governor, is in a far fifth place in the latest Quinnipiac poll, getting four percent and trailing Ted Cruz, Marco Rubio, Ben Carson, and Donald Trump.

Trump, the businessman from New York, remains in the lead at 24 percent support among Republicans but Carson, the retired neurosurgeon from Baltimore, is statistically tied with him at 23 percent. And in hypothetical general-election contests, Carson has a large lead on the leading Democratic candidate, Hillary Clinton, 50 percent to 40 percent. Much of that comes from Carson’s support from women voters, who prefer him to Clinton, 45 percent to 44 percent. Trump, on the other hand, is the only Republican to lose to Clinton, 43 percent to 46 percent.
