There’s a lot to like about Herman Cain. He’s funny and personable. He’s a great American success story. His 9-9-9 tax plan may be half-baked, but the concept behind the plan — replace the corporate income tax with in effect a consumption tax — has a lot to recommend it. (Although, the plan has a lot of problems, too.) Finally, in a political cycle that has seen too many coded racial attacks on President Obama and his family, it’s a source of great pride to me to see an African-American topping my party’s polls.
