That Obama has been worse
That Obama has been worse than Bush on some issues, for example foreign policy, is an argument Chomsky has made himself, so I don’t see how you can offer it in support of an argument against him. The key point in that interview is this:”Obama is quite different from the Republican candidates, and the constituencies of the two political organizations differ, which helps lead to different policies. Over a long stretch, for example, working people have made out better under Democratic than Republican administrations …”Chomsky votes for the party that is most likely to lead to the most positive outcome for the working class, a decision he bases on the best available evidence and research. It’s not a hard point to understand. Indeed, I know most sensible SPGB members understand it perfectly well: privately, many SPGBers will admit that they prefer to see a Labour win than a Tory one (you’d have to be mad not to), and I have known a few members admit to voting secretly for “lesser evil” candidates. Good on them.
