Well, Bruce Wayne likely could fund his own political campaign and run and win. Remember from the TV show when Batman ran against the Penguin?
Episode 52 - DIZZONNER THE PENGUIN 11/2/66 11/3/66.
Starring Burgess Meredith as The Penguin
"Plenty of girls and bands and slogans and lots of hoopla, but remember, no politics. Issues confuse people." -Penguin to his election crew
Written by Stanford Sherman. Directed by Oscar Randolph. The polls show overwhelming support for Penguin in his run for mayor, thanks to his rescue of a baby from a runaway carriage, a contribution of $100,000 to the Gotham City Charity Fund and other equally outstanding efforts. Since the only alternative to Penguin for Mayor is Batman for Mayor, the Caped Crusader enters the race, but cannot match Penguin's flair, snappy jingles and willingness to kiss babies. Batman and Robin are waylaid and strung up over a vat of acid.
