With regard to economic policy.I agree with Noah Smith.
Four years ago I agreed with Paul Krugman that Obama was being naive in believing he could get Republicans to do anything on a bipartisan basis.
That turned out to be true. I find it amusing to hear Republicans criticising Obama for 'not reaching out' to them.
Obama's mistake was being far too conservative with regard to the economic stimulus he asked for.
One really doesn't know what Romney would do. Would he indulge in 'expansionary austerity' or simply boost the deficit as both Reagan and Bush did in good times. I think probably the latter.
