Anthony Pappas, Republican
Elizabeth Perri, Conservative
Neither can win even with O-C and Crowley splitting the liberal vote (and either Pappas or Perri dropping out).
Has an elected representative ever declined election? What happens then?
The case of Mel Carnahan comes to mind; he died prior to election. I suppose officially that the (US Senate) seat was declared vacant and the governor appointed his wife until the next regularly scheduled statewide election.
In a Louisiana runoff, if the winner of the primary declines the runoff, the other candidate automatically wins. This happened in a local judgeship - I assume the same process might work in a US House race but I’m not sure.
Similar case in Vermont - if a winning gubernatorial (maybe any state row office) candidate gets less than 50% of the vote, the election can go to the state legislature (maybe only the state senate?). However the 2nd place candidate waived his rights and allowed the 1st place candidate to win by default.
Again that’s not quite the same thing as winning a US House race and declining the victory.
