Nah, Dogbert is more of an unelected power behind the throne guy. He fits more behind the Federal Reserve (The real power in the USSA).
While Wally is more like the presidents we have had in the last 20 or so years.. Although he has wits, so he wouldn't need to be reading the teleprompter all the time. And again, war would be too much of a hassle to him, so he would be an overall improvement over Bush and Obama.
Dogbert seems the more natural politician since things will actually get done, it's just a matter of what those things are. Wally would just sit by and let everything fall to bits around him since he is too lazy to do anything.
Could be worse, could be Donald Trump, I hear you need to declare your businesses bankrupt 5 times to be able to even look up to him... cas you know, that's how successfully Trump is.
