Political betting is not new in the market and I don't know any reason on why people should avoid it. If other people don't think it entertaining or unethical on their side then they should avoid it.
You are right but isn't available in many providers and regions. So even if gamblers want to bet, they simply can't.
Also for sure the casino would know if there's lack of interest on Political betting and for sure if they see that there's no people betting or had a little demand for this betting option then for sure that the casino would provably take out this option since for sure they don't want to waste their time and money for an option that doesn't get any profits for their casino.
Casinos' main (and probably only) interest is to earn money through gambling. Either that means games or events. We have seen bookies offering odds and markets for almost unbelievable things but hey, gambling is everywhere and for anything. If a casino gets even one more customer, is profit.
