A poll conducted earlier this year by McLaughlin & Associates shows that Congressman Kuhl now has a sizeable lead (a 20 point advantage) over Massa. According to this poll, Congressman Kuhl continues to build confidence with the voters, while Massa's favorable/unfavorable ratings are almost even.
Here's a quote from the NRCC on the poll:
"Rep. Randy Kuhl has been working in Congress to improve the economy and to meet the needs of families in New York's 29th District. And, as the numbers in this polling memo illustrate, Randy Kuhl is well-positioned to win in November. Eric Massa is a re-run candidate that now will carry the weight of a Democrat Congress that has voted for new taxes and increased spending at every turn on his shoulders," NRCC Spokeswoman Julie Shutley said.
