His catch phrase is, "Vote for me!", which he says every time he gives a speech. Mayor White is a cheery and friendly man, but is notoriously unhelpful, in terms of helping the town of Bluffington. He's more interested in telling others to vote for him, rather than giving them legitimate reasons for his election. As an example, after revealing his plan to "beautify Bluffington", citizens complained of trash and pollution, which only made the situation worse. He openly hates people who he knows didn't vote for him. Once, he (oddly and unfairly) fired the English teacher, Ms. Krystal, when his son said she didn't vote for him in the last election. (Realistically, a principal cannot fire a teacher, only the school board can.)
Bud Dink's wife, Tippi, replaces him as mayor in "Doug Runs". He went on to become the principal of Beebe Bluff Middle School. However, that didn't stop him from trying to become re-elected, which ultimately didn't happen.
Bob has darker skin, almost like Patti Mayonnaise, and has white hair (or possibly a wig, as it has been shown to fly off his head any time). He wears a blue suit with a red tie and black dress shoes.
Although it isn't discovered until later in the series (Doug Runs), Willie White, a member of Roger's gang, is his son. Despite being from a political background, Willy made a bad choice in judgement of hanging with Roger and his gang. Willy and Robert get along well, as he funded his campaign platform at school, while trying to maintain his own platform against Tippi Dink (in which they both lost).
Apparently, his wife makes all the mayoral decisions, which gives Robert the appearance of a timid, indecisive Mayor. Whenever there is a crisis, he knows his wife will get him out of it, as seen in Doug, Mayor for a Day.
There are various paintings in Robert's office, presumably of past mayors. They all have a similar appearance to him, so it's possible they're his ancestors.
- His voice is similar to U.S President George H. W. Bush, the father of George W. Bush.
- In Doug's Secret Song, it is revealed he is a member of the Yodeler's Society of Bluffington.
- His voice actor was Greg Lee, who was the host of the PBS game show, Where in the World is Carmen Sandiego?.
