A new Siena poll finds Democrat Scott Murphy taking a 4-point lead in the March 31 special election for New York's 20th District. Republican Jim Tedisco led by 4 points in the previous poll, released March 12. Tedisco had held a 12-point lead in a Feb. 26 poll.

Murphy's support among Democrats has risen by double digits since the February poll, when 60% of voters had no opinion of him. Tedisco's support among Republicans, however, has remained steady, with less than two-thirds of backing him.

Murphy 47 (+6 vs. last poll, March 12)
Tedisco 43 (-2)

"This remains a very tight race, with intense campaign activity on both sides,” Siena spokesman Steven Greenberg said.
