How did we get to the point where we have only a whopping two choices for President?

Title says it all. I just don’t get it. Yes, I understand there are others running, but they don’t even get to partake in the debates, let alone have any shot at winning the election. And when you think about it, isn’t it really outrageous that we have TWO choices? We have more choices than that for literally any other decision we ever have to make. Why, such an important one, we are given only two? Will there ever be a third party that has a chance? A fourth party? A fifth party? Might help with people voting for someone they actually support rather than the “less of two evils” which seems to be the case for a lot of people.

I hate politics. This isn’t meant to be an argument…I know fairly little about it and mostly that is because I choose to. I find it upsetting, and am asking this question innocently. I really do want to know how it got to this point. 2 options. Seems so ridiculous.
