No, it does not force you to do anything of the sort. That frustrates me so much. Voters choose to do so even if they think there is another, better candidate. It is entirely on the voters, period.
Any voter who would prefer some 3rd person that isn't listed but votes for one of the two main ones instead of writing in their preferred choice, or even a 3rd person that IS listed but they choose not to vote for because they don't think the 3rd can win, is being untrue to themselves.
If there is a problem with our elections, it is because voters bring about the problems themselves.
It's a false choice at best because the playing field is absolutely rigged. It's the one thing the two major parties can actually agree on.
