He's certainly trying hard, spinning hard that it's a failure in wake of recent floods (and crying "media conspiracy" when confronted with facts that argue otherwise) and trying to stick the "Wisconsin's biggest polluter" label on Tom Barrett. Charlie has been on topic for at least two weeks, including on Sunday INCITE!, an impressive level of focus for Chuck (who often says he isn't going to let an issue go ... and then does). A level of focus, that suggests at least to the Brawler, that he may be in cahoots with others who see it as a potential knock on Barrett and counter to the "Walker is incompetent" theme.
Bruce Murphy seriously put the smack down on Charlie on this issue a couple years ago. He noted that the Milwaukee Journal Sentinel's taking a more fact-based approach to Deep Tunnel took the oxygen out of Charlie's rhetoric. One wonders if that will hold. After all, a misleading ad inspired by this misleading ad would be pretty easy to pump out.
