When Stephen Colbert briefly toyed with running for president four years ago, there was a certain amount of criticism from people who said he was demeaning what ought to be a serious process, no matter how much the campaigns and candidates might work to demean it themselves. The argument wasn't entirely without merit, though whatever damage was done was probably outweighed by the satirical value to be gained. And this year, in the wake of the Citizens United decision, wherein the Supreme Court essentially lifted nearly all restrictions on campaign spending by those seeking to buy elections, the need for satire is greater than ever.
