Another losing strategy was clinging onto not taxing people who make over $250K. When in fact Obama was going to expire the 2003 tax cuts which will raise the federal income tax rates on everyone including low income and middle income. Did McCain ever mention that? Nope! Instead McCain got rope-a-doped with the $250K figure and made himself look like the stereotypical rich evil Republican only out to protect his rich evil friends. The Democrats' duped the McCain campaign good with that one.
I think Obama saw this. In some of his radio commercials, he said (to paraphrase) "Don't ask yourselves if you're better off than you were four years ago, but if you will be better off." He saw the implications. Too bad McCain and the GOP didn't.
