"Blue" Dogs or Republicans?

A couple interesting SPSS outputs (of course I'm not revealing everything I have).

Partisan Voting Index Scores Among Democrats Elected in 2006 and 2008
	Mean	N	Std. Deviation
Blue Dogs	5.46	24	5.942
Progressives	-16.12	17	11.973
Total	-3.49	41	13.909
Cook PVI Scale - 40 (liberal) to + 40 (conservative)

For the not political nerds: These indices demonstrate that among NEW Blue Dogs (those elected in 2006 or 2008) 1) Obama lost their Congressional district compared to Progressive districts and 2) they barely won. The CPVI score is a good confirming variable. Also, check out that ideological cohesion (as measured by the sigma.) It's the stuff young polisci student's dreams are made of.
