If you've watched any kind of election coverage over the past few decades you know the emphasis campaigns place on winning in Iowa.
The Hawkeye State is the first real litmus test for candidates hoping to become president and helps voters gauge where the candidates stand in terms of popularity.
With the Iowa caucus coming up on Feb. 3, the first in the country, we want to know if the results in Iowa typically line up with who the two parties' national conventions choose to be the nominee.
Republican - Ted Cruz
Democrat - Hillary Clinton
Ted Cruz won the Iowa Republican Caucus at 27.6%, with now President Trump garnering 24.3% of the vote and Florida Senator Marco Rubio third with 23.1%. Trump was ultimately the nominee.
On the Democratic side, Hillary Clinton bested Bernie Sanders by just 0.3% and went on to become the Democratic nominee.
Republican - Rick Santorum
President Obama ran unopposed on the Democratic side of the ticket.
Meanwhile, Rick Santorum won Iowa over Mitt Romney by just 0.1%, however it was Romney who ultimately became the nominee.
Republican -Mike Huckabee
Democrat - Barack Obama
Mike Huckabee had a solid win in Iowa, with 34.4% of the vote. However, the man who would ultimately become the Republican nominee was John McCain, who got just 13.1% of the vote in Iowa.
President Obama won in Iowa with 37.6% of the vote and ultimately won the nomination and the general election.
Democrat - John Kerry
President George W. Bush ran unopposed on the Republican side.
For Democrats, John Kerry won the primary with 37.1% of the vote in Iowa and went on to become the nominee.
Republican - George W. Bush
Democrat - Al Gore
George W. Bush and Al Gore both won in Iowa and eventually became their party's nominee.
Republican - Bob Dole
President Bill Clinton ran unopposed for a second term.
Bob Dole won at the Iowa caucus and went on to be the Republican nominee.
Democrat - Tom Harkin
President George H.W. Bush ran unopposed for a second term.
In what will seem like the most surprising stat on this list, eventual President Bill Clinton received just 2.8% of the vote at the Iowa caucus. Instead it was a man named Tom Harkin, who had strong Iowa ties, that got a whopping 76.5% of the vote there.
Republican - Bob Dole
Democrat - Richard Gephardt
Bob Dole was the Republican nominee in 1996 and won the primary in Iowa in 1988, however it was George H.W. Bush who won the 1988 Republican nomination despite coming in third in Iowa
Democrat Richard Gephardt won in Iowa with 31.3% of the vote, but it was Michael Dukakis who became the nominee despite coming in third in Iowa.
Democrat - Walter Mondale
President Ronald Reagan ran unopposed for a second term on the Republican ticket.
For Democrats Walter Mondale won Iowa by a healthy margin and did become the nominee.
Republican - George H.W. Bush
Democrat - Jimmy Carter
George H.W. Bush did eventually become president, but this wasn't the year. Despite Bush winning in Iowa, Ronald Reagan ultimately became the nominee and president.
Jimmy Carter was the incumbent and did win Iowa, but there was still a caucus.
According to the Des Moines Register, since 1972 the top voter-getter in the Democratic caucuses has gone on to win the nomination in seven of 10 contested races, but just Jimmy Carter in 1976 and Barack Obama in 2008 won the presidency. Among Republicans since 1980, the winner of the Iowa caucuses has gained the nomination in three of eight contested races, but the presidency just once: George W. Bush in 2000.
While Iowa may not always pick the nominee or the president though, Iowa's caucuses do help narrow the field for voters around the country.
Two Iowa Democratic Presidential Caucus polls were released Wednesday:
A Monmouth poll has Joe Biden in the lead with 23% of the vote with Bernie Sanders close behind at 21%, followed by Pete Buttigieg with 16%,Elizabeth Warren at 15% and Amy Klobuchar at 10%.
An Iowa State University poll however puts Sanders on top with 24% of the vote, Warren in second with 19%, Buttigieg with 17%, Biden with 15% and Klobuchar at 11%.
Iowa Democrats go to the polls on Monday.
