We have now watched McCain run twice for president. The first time he positioned himself as a principled centrist and decried the politics of Karl Rove and the influence of the religious right, imploring voters to judge candidates "by the example we set, by the way we conduct our campaigns, by the way we personally practice politics." After he lost in 2000, he jagged hard to the left - breaking with the president over taxes, drilling, judicial appointments, even flirting with joining the Democratic Party.
