Holding a special election to fill the seat vacated by Republican Chris Collins on the same day as the state’s presidential primary would give a Democratic candidate an “unfair advantage” in the race, New York Republican Chairman Nick Langworthy said on Thursday.

“It’s disrespectful to the taxpayers of that district,” Langworthy said. “Call a special for January.”

Collins resigned last month as he entered a guilty plea in his insider trading case and resigned his seat a day earlier.

Gov. Andrew Cuomo has indicated he will call the special election for April 28, the same day as the state’s presidential primary as a way of saving money on the election.

Langworthy’s concern is having the special election and the primary aligned would drive out more Democratic voters in an otherwise heavily Republican district. President Donald Trump is not expected to face any meaningful opposition in the GOP primary; the Democratic primary field could still remain unsettled by that time.

“It would give them an unfair advantage because there’s a built-in turnout mechanism based around the presidential election to figure out who is the most left-wing socialist to represent their party in a national election,” he said. “I should expect no more from Andrew Cuomo than to try to put his thumb on the scale.”

Multiple Republicans are vying for the GOP nod in the district, which encompasses parts of western New York.

Langworthy, in Albany to speak with reporters at a news conference ripping the state’s public financing commission, said Collins should have stepped aside in 2018 when he was first charged. Collins narrowly won re-election against Democrat Nate McMurray who is running again.

Langworthy said he wishes the seat was not vacant while Trump is facing an impeachment drive in the House of Representatives.

“The only thing I wish out of the whole thing was that he would have come out off the ballot in 2018 so we could have had someone in Congress as the president is facing impeachment who would be there to represent the most Republican district in the state of New York,” Langworthy said. “Right now we have no voice for the people in those counties and that’s a shame.”

Updated: Rich Azzopardi, a senior adviser to Cuomo, shot back at Langworthy.

“While the New York GOP fretting about losing another race isn’t new, this is a different issue and no date has been set yet,” he said. “If Langworthy tended to his own backyard in the first place and didn’t enable Wall Street fraudster and full-time Florida Man Chris Collins , we wouldn’t be here.”
