I think it will be Perry vs. Obama. All the other 'official' GOP candidates are trying to break out to lead the pack, and Perry has intentionally kept himself apart and separate from the pack for as long as possible. All this 'I'm thinking about running...I'm considering running' BS is just what he's telling the press.
They say Perry is the luckiest guy in politics and a superb, shrewd campaigner. People will mistakenly think he's another Bush because he's another Republican Governor from Texas. But he's really very different and strikes me as being much more like Reagan than Bush. And if US key indicators continue to slide until election day (God-forbid), we're gonna need a faith-filled cheerleader to feed America confidence until it's on its feet and running again....a la Reagan.
Like the rest of you, I'm really looking forward to this campaign. It's going to be like the Super Bowl, World Series and World Cup all rolled into one with much higher stakes. The battle will be shaped by existing conditions (debt, unemployment, spending), candidate self-destructions, campaign implosions and probably a few surprise outside influences.
