Kevin's made the point before, and repeats it today, that Democrats have to run to the center more than Republicans because more people identify as conservative than liberal and therefore, they have to appeal to fewer "moderates" or people in the center than the Democrats do. Or put another way, since there are so many more people in their base, they have to pander to it to win while the Democrats have to pander to the center in order to get a majority.
The problem with this analysis is that he thinks all this has something to do with how people self-identify, as if the people who identify as "conservative" are all really conservative or the moderates and liberals are truly moderate and liberal. I don't know that that's the case. Sure it's true in some cases, but I don't think people necessarily identify with these ideological labels out of ideology. It's more of a tribal ID or a social designation.
And I think it's fairly clear that a huge propaganda campaign to demonize the word liberal that has lasted nearly 30 years has taken its toll on the willingness of people to wear it. Even I, old time lib that I am, have found myself in large social and business situations in which self-identifying as a liberal is uncomfortable....
Boy howdy! As they say in the trade. The GOP just voted to block discussion of the Defense Authorization Act. If Dems had done this, the only thing you'd hear for the next week would have been, "Why do the Democrats hate the troops?" And yet, not only do the Democrats not even dream of making such a politically potent attack on Republican obstructionists, the Republican senators are acting in defense of a position that even a majority of Republicans oppose. How, exactly does Kevin Drum's reasoning explain that? Simple: It doesn't.
