I understand the US doesn't have a lot of choice on the ballot
That is not at all true. Sure there may only be two parties with one candidate each on the national level (assuming you don't get involved with the primaries), but in the US a lot more local positions are elected (which in many ways have a much greater effect on your day to day life) and local referendums (or ballot initiatives) are very common.
