Baring any last-minute scandal or divine intervention, it's a safe bet to assume that John McCain will be the Republican candidate for president. The picture on the Democratic side is far less clear. One thing is for certain, though, Super Tuesday is going to be a dogfight on both sides.The Arizona senator, a genuine War hero who has forged alliances with Democrats when needed, may be the GOP's best hope of retaining the White House, though chances of that happening are probably remote. McCain is trying to court voters worried about the economy through his calls to abolish the AMT, fight wasteful spending and to keep taxes low. He is gaining some big endorsements including one-time rival Rudy Giuliani and California Gov. Arnold Schwazanegger. Mitt Romney is losing ground to McCain in part because Mike Huckabee is siphoning off support from social conservatives.
