ABC: ‘Troubling’ New Poll for Clinton Shows Her Smallest Lead Yet in Iowa

ABC reported Sunday morning on a "troubling" new poll for Democratic frontrunner Hillary Clinton in Iowa showing her advantage there has shrunk to its lowest level yet.

A new poll shows Clinton's lead in the same state where then-Sen. Barack Obama won a stunning victory over her in 2008 has fallen to just seven points over Sen. Bernie Sanders (I., Vt.), 37-to-30. Vice President Joe Biden, who is not a declared candidate, polled at 14 percent.

The Des Moines Register reports this was "the first time Clinton, the former secretary of state and longtime presumptive front-runner, has dropped below the 50 percent mark in four polls conducted by the Register and Bloomberg Politics this year."

"That new poll has some troubling signs for Hillary Clinton," ABC reporter Devin Dwyer said. "She's lost a third of her supporters in Iowa since May. Many Democrats considering their alternatives, including a man not even in the race, Joe Biden."

Biden made an unannounced visit to the Sussex Democratic Jamboree in Delaware on Saturday, which added to speculation in recent weeks that he may jump into the race.

Biden was a senator from the state before being elected vice president, and he went to thank Democrats there for their support. According to ABC, he did not discuss a potential 2016 bid.
