Joe DioGuardi, the former Westchester County Congressional representative who lost to Sen. Kirsten Gillibrand in 2010, today endorsed Republican hopeful Wendy Long.

“Our nation is in a fiscal crisis unsurpassed since the Great Depression,” DioGuardi said. “We need bold and decisive action in Washington if we are to put Americans and New Yorkers back to work. Wendy Long is a fiscal conservative who will fight to cut spending, lower taxes, and shrink the ever growing national debt. But, most importantly, she is the only Republican who can defeat Kirsten Gillibrand, and that is why I am endorsing her for U.S. Senate.”

DioGuardi narrowly won a three-way Senate race against economist David Malpass and Nassau County Legislator Bruce Blakeman.

He was soundly defeated by Gillibrand, who was running for the remainder of Hillary Clinton’s six-year term, 63 percent to 35 percent.

DioGuardi’s campaign achieved some minor buzz outside of New York due to his daughter, Kara DioGuardi, was at the time a judge on American Idol.

Long is in a three-way primary herself this time out, running against Rep. Bob Turner and Nassau County Comptroller George Maragos.
