The latest polls conducted in Iowa, the state set to register the first caucus, by a variety of agencies show Hillary Clinton losing ground to Bernie Sanders. The Des Moines Register/Bloomberg Politics poll shows Clinton leading Sanders by a miniscule two percentage points. Clinton leads Sanders 42 percent to 40 percent, a sharp decline from a month back, when Clinton had a clear nine-point lead.

"It shows Bernie is around to stay for sure. It's not a fly-by-night thing. It really shows we're going to have a pretty crazy last few weeks here," said Grant Woodard, a Des Moines lawyer and veteran volunteer of many Democratic campaigns, reports USA Today.

"As we get closer, sometimes things get more volatile, rather than less," said Ann Selzer, an Iowa Poll conducting officer, according to USA Today.

A separate poll conducted by Quinnipiac University and released on Jan. 12, shows Sanders leading Clinton with 49 percent support. Clinton managed to register 44 percent support. The lead is the highest Sanders has managed to date, and is a 9 percent increase for him.

"Anybody can win. Who would have thought Donald Trump is leading in national polls?" Clinton said, replying to a question on whether Sanders can win the presidency, reports ABC News.

The Monmouth University poll registered Sanders holding a 53 percent to 39 percent lead over Clinton, a 14-point lead between the contenders in the Hawkeye State.

"Democrats are much more likely than Republicans to say this is an election about issues, rather than leadership. That really explains the division in the party. Half of those who say this election centers on issues support Bernie Sanders, versus 37 percent for Clinton. Among those who say the election is about leadership, it's just the opposite. Half say Clinton is their first choice, versus 29 percent for Sanders," said Ann Selzer, explaining the situation, according to Bloomberg Politics.
