A new poll has good news for 'humble front-runner' Jeb Bush

A new CNN poll of the 2016 presidential race has former Florida Gov. Jeb Bush (R) "rising nationally," the news station reported Wednesday.

Bush holds 19% of the vote among Republican voters - which is up 13% from May, according to CNN.

Though 19% isn't a huge number, it's a solid showing considering that roughly 15 major GOP candidates are in the race. Only Bush and real estate developer Donald Trump, with 12%, have double-digit showings in the poll.

"The findings suggest Bush is making progress toward being seen as the frontrunner in a field that has long lacked a clear leader," wrote CNN's polling director, Jennifer Agiesta.

"He holds a significant lead over the second-place candidate Trump, is seen as the candidate who could best handle illegal immigration and social issues, and runs about even with Trump and well ahead of the other candidates when Republicans are asked which candidate can best handle the economy."

Brianna Keilar, a CNN political correspondent, further called Bush "the humble front-runner."

Bush and Trump weren't the only White House contenders to lead a poll Wednesday morning, however. A new Quinnipiac survey of Iowa found Wisconsin Gov. Scott Walker (R), who hasn't announced his candidacy yet, still in first place in the early primary state.

Peter Brown, assistant director of the Quinnipiac poll, noted in a statement that Walker's support slightly dropped compared to the university's previous survey.

"Iowa front-runner Scott Walker, the governor of neighboring Wisconsin, remains in front, but his support continues to drop," he said. "Meanwhile, behind Walker are a half-dozen wannabes who are fighting for second place."
