Overall, betting on political events is very exciting. In politics, you are always sure that this guy is going to win, you collect info from your friends, co-workers, what they think and etc. I wish there were other political events available too.
I only partially agree with you.
Agree: Betting on political events is very interesting. It's true if we know that in life, there are something that you should never talk about, and one of them is politics. It is very controversial and can create conflicts between you and other people even they are your family members, friends, colleagues, etc.
Disagree: It's not easy to know who will win an election. Even nominees in an election won't be sure about election ending so you are as an outsider, can not be sure about it. You can collect information around, but it can not give you absolute accurate answer for a winner of an election.
I don't know if it's a coincidence but I've been guessing political outcomes of my country and the USA for over a decade. I find it easy, it's easy to talk with people and understand their political stances. I often meet people and when I'm in groups and see that the majority of people support one political party and that's repeated in many different groups, then I'm sure there which party is going to win.
The situation with the USA is different. I don't live in the USA but I read posts and comments about people's vision of US political parties and it was clear to me that Trump was going to win this time, I even made a bet on him months ago. Maybe I'm lucky and my confidence is caused by it, I don't exclude that.
