According to a Quinnipiac University survey released on Wednesday, Sanders takes 49 percent support over Clinton at 45. That’s essentially unchanged from the same poll released two weeks ago, in which Sanders led 49 to 44.

“Is this deja vu all over again?  Who would have thunk it when the campaign began? Secretary Hillary Clinton struggling to keep up with Sen. Bernie Sanders in the final week before the Iowa caucus,” said Quinnipiac polling director Peter A. Brown. “It must make her think of eight years ago when her failure in Iowa cost her the presidency.”

Polling for the Iowa Democratic caucuses has been all over the place, but recent surveys indicate a photo finish on Feb. 1. Clinton leads by less than a point in the Hawkeye State, according to the RealClearPolitics average.

Former Maryland Gov. Martin O’Malley takes 4 percent support in the new survey.

Iowa voters are close to finalizing their decisions, with19 percent saying they could still change their minds and only 2 percent saying they remain undecided.

There are massive gender and age gaps between Clinton and Sanders.

Sanders leads among men by more than 30 points, while Clinton holds a 14 point advantage among women in Iowa.

Meanwhile, Sanders has a massive 78 to 21 advantage over Clinton among voters between the ages of 18 and 44. Clinton dominates 53 to 39 among voters between the ages of 45 to 64, and does even better among voters over 64, taking 71 percent support.

“Perhaps more than other contests, the Iowa caucuses are all about turnout,” said Brown. “If those young, very liberal Democratic Caucus participants show up Monday and are organized, it will be a good night for Sen. Sanders. And if Sanders does win Iowa, that could keep a long-shot nomination scenario alive.”

A strong plurality, 38 percent, said that the economy is the number one issue. Fifty-three percent of Iowa Democrats said they trust Sanders more on the economy, compared to 41 percent who said the same of Clinton.

Healthcare is a distant second place issue, with 17 percent calling it the most important. Clinton leads Sanders there 50 to 44.

The Quinnipiac University survey of 606 likely Democratic caucus-goers was conducted between Jan. 18 and Jan. 24 and has a 4 percentage point margin of error.
