Reason Behind Stefanik’s Decision to Leave Congress, End Governor Bid

That calculation changed after Nassau County Executive Bruce Blakeman, a Trump ally, entered the Republican primary.

The source said Blakeman’s entry made it clear Stefanik would face a contested primary.

The source said Trump’s neutrality, combined with the prospect of a prolonged primary, factored heavily into Stefanik’s decision.

“When you start to add these things up, it does not seem that you’re going to have the wind to your back in this cycle,” the source said.

The source said Stefanik’s decision to leave Congress was also driven by a sense that it was time to move on.

“I am truly humbled and grateful for the historic and overwhelming support from Republicans, Conservatives, Independents, and Democrats all across the state,” Stefanik said.

Stefanik has been one of Trump’s most loyal allies in Congress and defended him during both impeachment proceedings.
