It’s been 90 years since someone with a criminal conviction was elected to the House. But one felon could jump-start his congressional comeback if he wins a Republican primary next week.

GOP voters in New York’s 11th District head to the polls Tuesday to choose between Rep. Dan Donovan and former Rep. Michael G. Grimm, who resigned his seat in early 2015 and served seven months in prison after pleading guilty to tax evasion.

While Donovan has referenced Grimm’s conviction as an example of the former lawmaker’s dishonesty, much of their primary battle has centered on who represents the better ally for President Donald Trump. The president is popular in the district, where his brash style appeals to voters in the ‘Forgotten Borough’ of Staten Island.

Trump has weighed in on the primary, backing Donovan, but Tuesday’s election could be a test of the president’s political power among his base supporters. And the GOP primary result could determine whether the seat is in more danger of a Democratic takeover come November.
