A new Des Moines Register/Bloomberg Politics poll shows Bernie Sanders trailing Hillary Clinton by just 7 percentage points:
This is 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.
Poll results include Vice President Joe Biden as a choice, although he has not yet decided whether to join the race. Biden captures 14 percent, five months from the first-in-the-nation vote Feb. 1. Even without Biden in the mix, Clinton falls below a majority, at 43 percent.
"This feels like 2008 all over again," said J. Ann Selzer, pollster for the Iowa Poll. [...]
The vice president saps support from both Clinton and Sanders, the poll shows. Without Biden in the mix, Clinton is at 43 percent and Sanders is at 35 percent.
"So, Biden takes 6 points from Clinton and 5 points from Sanders," Selzer said.
Other recent Iowa polls have shown Clinton with a much larger lead, but the Des Moines Register poll is widely considered to be the gold standard in Iowa. The last two polls in New Hampshire show Clinton trailing Sanders by 7 points.
