Dede Scozzafava Endorsement
Newt has admitted it was a mistake to back Dede Scozzafava, the Republican nominee in the 2009 NY-23 special election.
Whether it was helping to build the Republican Party of Georgia back when Democrats controlled the entire state or leading the nationwide effort in 1994 to break 40 years of Democratic rule in the House, Newt has always tried to advance the cause of a truly conservative Republican party. This has always meant supporting the most conservative nominee possible as selected by Republican primary voters.
Therefore, Newt will almost always back the nominee of the Republican party and not back an independent candidate in a race against a Democratic candidate.
Newt still believes in this principle, however, he has admitted it was a mistake to back Dede Scozzafava, the Republican nominee in the 2009 NY-23 special election. Although she was the Republican nominee, the problem was that Republican primary voters did not pick her, the local party leaders did, otherwise her liberal views would have prevented her from becoming the nominee. The Conservative Party candidate whom Scozzafava was running against, Doug Hoffman, recently remarked about Newt’s endorsement of his rival, “I would advise other conservative republicans: Don’t hold this against him.”
A district 23 endorsement would be nothing in a general election, people would not even know what they were getting at, endorsing Romney could have a little effect though.
Here are some who endorsed her.
House Minority Leader John Boehner (R-Ohio), Minority Whip Eric Cantor (R-Va.), National Republican Congressional Committee (NRCC) Chairman Pete Sessions (Texas) and Rep. Kevin McCarthy (R-Calif.), who is in charge of recruiting candidates to run next (that) year and Rep. Jeb Hensarling (R-Texas).
