There's been a lot of talk lately about Barack Obama switching sides on key issues, and this has prompted the old tired calls from many on the right (and even some on the left) to decry Obama for being "all style and no substance."

While I plan to address the "flip-flop" issue on Monday, About.com guest writer Jack Kerwick tackles the "style" vs. "substance" argument in this week's "Friday's Guest Column."

From the article:

The truth is this: Obama is indeed a radical, and unquestionably the most radical presidential candidate this country has ever seen. His speeches, designed as they are to conceal this, consist of exceedingly vague generalities that render them, at least to the untrained ear, woefully vapid. But that is the point: his speeches wouldn’t need to place a premium on “style” if the “substance” of his views didn’t so offend mainstream American sensibilities.

And he knows it.
