But her unwillingness to take a position on the Trans-Pacific Partnership, a proposed trade pact vehemently opposed by labor, has made some union leaders and workers wary.

Mrs Clinton directed last week that the server be turned over after the Federal Bureau of Investigation requested it.

Hillary Rodham Clinton is getting endorsements from two former Democratic governors in the early-voting state of South Carolina, including one who helped lead President Barack Obama’s first campaign. Most Democrats, though, say they’d like to see Biden make a run for the White House.

At the same time, Vermont Sen. James Webb sits at 1%.

Should Biden decide not to make a run for the presidency, his supporters would largely flock to Clinton rather than Sanders, boosting her numbers.

Jensen said most recent polls put Clinton’s support among African-American voters at around 70% to 80%.

Clinton still holds a strong national lead, with 49 percent support, but Bernie Sanders is starting to gain major traction.

At the Wing Ding fundraiser, a high-profile gathering of Democrats in northern Iowa, Sanders rattled off the names of shooting victims in Ferguson, Missouri, Baltimore, New York and elsewhere.

“When I look, Chris, at what happened with Petraeus… great general, wonderful guy, everybody loved him, and it destroyed his life over much less”, Trump said.

According to the latest figures, Clinton enjoys support from 47 percent among Democrats, Sanders scores 29 percent, with Vice President Joe Biden at 14 percent.
