(CNN) - He's a Republican on the ballot, but not on the airwaves: GOP state assemblymen Jim Tedisco, running for the open seat in New York's 20th congressional district, is quoting President Obama in his latest ad.
"Like the president said, in these difficult times, we're not Republicans or Democrats, we're Americans," he says in the 30-second spot. "And that's the team I'm on."
Tedisco's former double-digit lead over Murphy has shrunk to 4 points in the most recent Siena poll, released last week.
Yesterday, the Republican National Committee sent another $100,000 to the state party as the race enters the home stretch. The special election is set for March 31.
