Kim, a former national security official, said he was inspired to run because of MacArthur’s role in helping House Republicans pass a bill that would have repealed and replaced ObamaCare.

Viral videos from a MacArthur town hall last year foreshadowed what was to come: angry voters berated him for authoring an amendment that helped Republicans secure the votes necessary to get the bill through the House.

MacArthur also faced criticism for being the only New Jersey Republican to vote for the GOP's tax bill, which capped state and local tax deductions at $10,000. 

New Jersey, which has some of the highest property taxes in the country, is one of the states that benefited most from unlimited deductions on state and local taxes.
