President Obama’s State of the Union address soared  right over a familiar cliff.

The president simply couldn’t seem to escape his professorial past, to convey his passion and convictions in the plain words of plain folks, and to breach the chasm between the People’s House and people’s houses.

He’s still stuck on studious.

He seems to believe that if he does a better job of explaining his aggressive agenda, then he’ll win hearts and minds. It’s an honorable ambition, but it’s foolhardy. People want clear goals, clearly defined and clearly (and concisely) conveyed. They’re suspicious of complexity.

H.L. Mencken once famously opined, “No one in this world has ever lost money by underestimating the intelligence of the great masses of the plain people. Nor has anyone ever lost public office thereby.” I take exception to that. But if you change “intelligence” to “attention span,” I agree wholeheartedly.

Republicans know this well. Obama knows it not.

Take the enormous health care bill for instance. The president overreached, pushing a convoluted bill with a convoluted message. The Republican response: “Just say no.” They countered with a series of crisp attacks that shrouded the bill in a fog of confusion. Now it’s in danger, and the public may well blame the Democrats. People don’t care as much about process as they do about results.
