Iowa's been a swing state in presidential elections for years, and true to form, it looks like it could be that way again in 2016.
A new Quinnipiac poll released Monday found Democrat Hillary Clinton, the former Secretary of State, tied with Republican Chris Christie, governor of New Jersey, in a trial run. Each had 41 percent.
Each rolls up big margins among party loyalists, and split the independent vote.
Vice President Joe Biden, another possible Democratic contender, trails Christie, 49-32 percent.
The poll also matched the Democrats with Wisconsin Gov. Scott Walker. Clinton beats Walker, 46-39 percent, while Biden trails 42-39 percent.
Iowa is a key presidential election state. Not only is it traditionally the site of the nation's first party caucuses, it's been considered too close to call in general elections. Obama won the state with 54 percent of the vote in 2008 and 52 percent last year over Republican Mitt Romney
The poll also found Iowa voters disapprove of the job President Barack Obama is doing, 55-41 percent.
