Democrats with high hopes for the 2020 presidential seat are flocking to Iowa.

Among the Democrat hopefuls are Massachusetts Rep. Seth Moulton, New York City Mayor Bill de Blasio, Minnesota Sen. Amy Klobuchar, Ohio Rep. Tim Ryan, and Sen. Bernie Sanders (I-Vt.).

A few of the White House hopefuls have been seen on the news a lot, making them more recognizable to the public. However, they often do not have a connection with the public or, specifically, Iowan residents.

This rush of potential candidates to Iowa is evidence of how important this state is for caucus results, as well as for the candidates building a name and brand for themselves.

As Democratic strategist David Wade states:

“Iowa has taken on an outsized importance in the last several years for Democrats,” Wade said. “There used to be a myth that a Democrat could skip Iowa and win the nomination anyways, because Bill Clinton skipped the caucuses in 1992. But John Kerry in 2004 and Barack Obama in 2008 demonstrated that an early and unlikely win in Iowa could set the story for almost the entire primary season.”

“You have to start early,” Wade added. “It’s a state that rewards on-the-ground time and investment of resources and with a large Democratic field expected, every supporter in every precinct and county really counts. You want to be building those inroads early.”

One of the major “selling points” Democrats will be using in their speeches is their defiance against President Trump. Using this, it will likely be easy to draw a crowd in Iowa.

However, this isn’t the only thing in the candidates’ arsenal. Democrats will likely be attempting to attract working-class voters – a population that Trump had more success with than Hillary Clinton.

Despite this, it appears some candidates have a head start in winning over Iowa’s residents. Both Bernie Sanders and Joe Biden have support amongst the state’s residents. In fact, according to an Iowa Starting-Line poll, 70% of Democrats view Biden “very favorably.”
