It was clear from the onset that this was going to be an election cycle like no other— that we were going to hit early and hard. My stars, we’re under attack! The contenders were all aware of that. If they knew it, and we knew it, then you can bet Sarah knew it. The game has been on and the bench is emptied.
Obama is trying to run the Harry Truman "do nothing congress" routine of decades ago. There isn't anything especially new about it. Campaigns are ALWAYS rough and tumble and if you've been around for very long you should know that.
Palin does not know anything any other candidate doesn't know. The only difference is her negatives are astronomically bad and if she were planning to run for president she has conducted the absolute worst run up to announcing a campaign of any candidate I can remember in recent history. Quitting her job as governor, doing fluff RealityTV, hit and run appearances to grab media attention from other candidates, etc, has not worn well with Republican primary voters and the polls show this clearly.
She's not running.
