President Trump won House District six by 30 points in 2016. Democrats say their candidate — retired principal Rita DeJong — was outspent 10-to-1, but closed that gap by nearly 20 points. 

As of January 1, there were 7778 registered Republican voters in the district compared to 6617 “no party” or independents and 5013 Democrats.
