So here's the scenario. The Democrats who craft political strategy for the party have tried to figure out how to somehow use the Tea Party moment to provide an advantage to their base. When the Tea Partiers, collectively, are in economic libertarian mode, Democrats can't make much noise.
But when Tea Partiers are in "elect someone like Christine O'Donnell mode," Democrats sense an opportunity. Simply put, the crazier the Tea Party seems, the more Democrats can link the Republican agenda to its source of energy, which in turn fires up rank-and-file Democrats.
At this point, you're probably saying: "Thank you, Captain Obvious," or something less charitable. But the background is necessary because there IS a way, a sure-fire way, to energize the Democratic base, to even pull the attention of the "professional left" away from disappointment and criticism of Democrats for a moment.
Tying the mainstream GOP to the Tea Party is a topic under discussion in the White House. But how? Trying to make John Boehner a foil for the election, or even Jim DeMint, or even Glenn Beck, is like spending half of the amount you've budgeted for a nice wool suit. Instead of Dolce and Gabbana, you wear Kenneth Cole.
