There's been a blitz of TV ads in the past week paid for by Mitt Romney supporters trying to define President Obama for Pennsylvania voters.
You can hardly change channels without seeing another commercial paid for by a group other than the candidate's campaign.
Would it be so bad if the candidates' proxies spent as much time and money outlining the admirable traits of the person they want to be president? There's some of that, but too little.
Romney, in particular, should be filling in some gaps. Instead, with steps like refusing to release tax information that would help voters figure him out, he allows his opponent to tell them who he is. For example, it wouldn't be so easy for Democrats to call Romney "Robin Hood in Reverse" or "Romney Hood" if he would fill in the blanks on his tax plan.
