“I love that smell of the emissions,” - Sarah Palin at yesterday’s Rolling Thunder rally. I wish I could keep myself from posting about this sideshow, I mean slideshow, but her bike adventure is a loud, obnoxious cry for attention. But it's also a trial for 2012.

At the Daily Dish, Shushannah Walshe reports on the meaning of Palin's bus tour:

According to a source with knowledge of Palin’s operation and thinking, keep a careful eye on how long the tour lasts, because it is intended as a way to test the presidential waters. If the road trip ends abruptly, it’s a sign she didn’t get the enthusiastic responses she believes she needs to launch a campaign. If the tour heads to regions outside of the Northeast like Iowa and South Carolina that, the source says, is a “big indicator” that Palin will pull the trigger.
