The debate among Republican presidential candidates at the Reagan Library on Wednesday, Sept. 7th, provided a good deal of political theater. Every word spoken by the candidates, every facial expression, even their body language, enlivened the event. Brian Williams of NBC News and his cohort, John F. Harris, from Politico asked questions calculated to put each candidate on the spot. They especially wanted to pit Mitt Romney against Texas Governor Rick Perry. The result was quite a spirited combat that revealed the differences between the two candidates. Mitt Romney came across to this writer as a moderate Republican offering a good economic plan but not much else. He did not talk of repealing Obamacare, only issuing waivers. Hardly good enough for Tea Partiers. Michelle Bachmann, Herman Cain, and Ron Paul pledged to repeal Obamacare. Perry, however, got hung up on the Social Security issue. Romney pledged to save Social Security and make it better, which is what moderate Republicans always do with liberal programs. Perry called Social Security “a Ponzi scheme,” which sent Williams and Harris into convulsions of disbelief. A Ponzi scheme? It sounded off the wall but was nevertheless true.
