So, lets see:
You prefer liberal to conservative (both the ADA and ACU 2007 ratings of Specter indicate his voting record is more liberal than conservative. Interestingly enough, the ratings add up to 100),
I'm not a fan of the blanket "conservative" or "liberal" ratings, as they can often be deceptive... two Senators who voted the opposite way on every bill, covering a wide spectrum of issues, can end up with the exact same rating. That said, after briefly looking over the votes used to tabulate the ACU score, I don't think 40 is all that far from where I'd be... maybe I'd be around 50, but I don't know.
I've generally tried to avoid this issue, but I really don't feel like it anymore... yeah, I'm moderately pro-choice. That said, Specter's 2007 NARAL rating is an aberration (his 2006 rating was actually 50, but I assume you were talking about his 2007 rating)... his rating has generally been anywhere between 0 and 65 over the last decade.
His lifetime rating, on the other hand, is 49%. It's not a good score, to be sure, and Arlen has never been a strong opponent of earmarks... this is one of the reasons I qualified my remark with a (for the most part).
While the NRA gave him a lifetime rating of "A" in 2004... interesting
Oh, I did, and it was quite informative... thank you.
I've actually never twisted anything... I've made fun of you, but that's not really a Nixonesque deception, more like a middle school kid pointing and laughing.
I've also never read a list of your gripes with McCain... I'd be interested.
