Palin is now serving in her role as the enforcer or the attacker. Basically, she's Bill Laimbeer -- the four-time NBA all star who was notorious for his physical play. He'd rough you up with the goal of disrupting the game to get back on offense. Then again, sometimes he'd just rough you up for the heck of it.
Think of it as the last few minutes of a basketball game. Fans don't like it, but when a team is down the fouling begins. Purposeful fouls. The tactic is used to get the opposing team to the free throw line to stop the clock. If Shaquille O'Neal is on the free throw line, not only did you stop the clock - the odds are he'll miss the buckets. Your team gets the ball back with a chance to score.
It's an ugly way to wind down a game. But for the losing team, it's about the only shot they have. The question for the McCain campaign is -- how late in the fourth quarter is it?
The Obama campaign knows the score. Heck, in a conference call to reporters on Friday, a McCain official announced they were going to focus on "discussing Mr. Obama’s aggressively liberal record."
The challenge for Obama is not to allow the conversation to change.
"They'd rather try to tear our campaign down than lift this country up," Obama told a crowd in North Carolina. "That's what you do when you're out of touch, out of ideas, and running out of time. So I want all of you to be clear, I'm going to keep on talking about the issues that matter."
It's just campaigning
Like it or not, a campaign is sport. And people get very irritated when the media treat it that way. "This is not a game," they say. "This is the future of our country."
