That's a great question. Here's some more info on Scozzafava, the candidate that Newt, the RNC, etc. endorse (and the candidate that Romney and possibly Huck have declined to oppose):

Scozzafava is an abortion rights advocate who favors gay marriage. It would be one thing if Scozzafava balanced that social liberalism with fiscal conservatism. But as a state assemblywoman, she voted for massive tax increases, Democratic budgets and a $180 million state bank bailout. She also supported the trillion-dollar federal stimulus package — which every House Republican voted against.
More troubling, Scozzafava in past elections has embraced the ballot line of the Working Families Party — a socialist outfit whose political DNA is intertwined with scandal-ridden ACORN. ACORN and the WFP have shared office space in New York City, Arkansas and Illinois. ACORN head Bertha Lewis, a close Scozzafava friend and political supporter, wears a second hat as vice chairman of the WFP. The WFP has been listed in ACORN documents dating back to 2000 as an “affiliate.”
And that, ladies and gentlemen, is the bottom line. Our national party is NEITHER socially or fiscally conservative...and would support ANYONE who cares to don the GOP banner OVER a conservative of any ilk.
