Gambling platforms cannot avoid political events because from there is part of how they are making their money, when gamblers are betting on such events and activities, just as we already have it in the just concluded US presidential election, gamblers took bets on it and make fun out of it, we cannot also make gambling turned a political effect, but people are only interested on the events for the purpose of gambling.
For the purpose of gambling, is why so many people try out their luck when there are major events that could produce the opportunity to make quick wealth. I don't blame any gambling platforms that make out extra effort to include some major events that aren't just sports or horse racing, because in the end, a gambling platform aims to make money from the outcomes of events, it is just that sports betting or horse racing or basketball games are a more frequent event and as such, occupies a top spot for options a bettor can choose from.
Political events or other events that are remarkable can and should be made available to be bet on, that's from a legal platform.
