I particularly like his analysis of the current political environment, which he summarizes in this paragraph:
Candidates are catering to the obsessions of their bases and single-issue voters because they are the voters who reliably vote in primaries and general elections. Americans who find this unserious and profess “a pox on both your houses” attitude are less reliable voters, especially in primary elections. The upshot is that we get the candidates we deserve.
That is one explanation for why, election after election, we keep getting to choose the lesser of two evils. It looks like that could be our choice again in 2012.
