Health care is running front and center in the three Iowa races.

Iowa went Trump in 2016, which saw the Democrats blown out of the water that year. Iowa Democrats are seeking to un-fracture their party which saw supporters defect from establishment candidate Hillary to outsider Progressive Senator Bernie Sanders in the 2016 primary caucuses. In fact, in 2016, Republicans stole the state Senate, making the state a trifecta of GOP control beginning in the 2017 legislative session.

Governor

Incumbent Gov. Kim Reynolds is alone representing the Republicans. Two Democrats are facing off, and its business versus labor. Fred Hubbell, a business owner is up against Cathy Glasson, a labor leader. The third, state legislator Nate Boulton quit mid-race after a sexual misconduct scandal. These three candidates have widely divergent philosophies on health care, explained here, by Vox.

"Expect health care and Trump’s approval rating to come into play in this race. Reynolds’s signature achievement is probably moving Iowa’s 600,000 Medicaid enrollees into managed care, a privatized version of the program where private health plans administer Medicaid’s benefits. Hubbell wants to reverse that privatization, while Glasson supports a more liberal single-payer option."

Iowa’s third US Congressional District: Again, more healthcare.

Republicans are listing their incumbent, Rep. David Young, who voted to repeal Obama Care. Democrats are running three candidates: former Bernie Sanders campaign aide Pete D’Alessandro, former insurance executive Eddie Mauro, and Cindy Axne, a former small-business owner. This race is all about progressive visions of healthcare and moderate. Check out their platforms from the Des Moines Register.

Iowa’s first US Congressional District

In the eastern part of the state, it’s a four-way race for the Democratic spot in the November general elections.  Republican Rep. Rod Blum is the incumbent Republican incumbent.   State legislator Abby Finkenauer, is leading the way as, potentially, the youngest women elected to Congress in US history. This race makes Blum vulnerable to the Democrats.
