OK, this is hardly a shocking admission, and I know that David Frum was pretty much given the boot from the GOP a few years ago, but this is still an excellent summary of where the GOP currently stands from a not-quite-batshit-insane-GOP perspective.
There has always been a pool of Republicans who have doubted the party's radical turn. Until now, however, these Republicans have been quiet and passive. They came out to vote in 2010, but they did not join Tea Party rallies. They supported Mitt Romney in the primaries because he looked like a potential president, but they did not object when Romney fastened his campaign to the deadweight anchor of the Ryan plan. They look to Speaker Boehner and Leader McConnell to fend off the crazies in the caucus, but they did not understand that those leaders' strategy for "fending off" the crazies consisted of abject appeasement of the crazies.
Some of these more responsible Republicans are waking up at last. More must do so, many more, before the party can again become a positive force in American politics.
What you have to understand is that in the area I live--Bloomfield Hills, hometown of both Mitt & Anne Romney, as well as having a fairly large, high-income Jewish population--there's a lot of Republicans of the same build as David Frum, who was a George W. Bush speechwriter, AIPAC member and BoD member of the Republican Jewish Coalition.
You may dismiss him, but his mind works the same way as a lot of folks in this area, so it's worth reading to get some insight into how things are playing out in their heads. You know how Jews tend to break about 80/20 for Dems? I live amongst the 20%, for the most part.
The whole thing is worth a read.
