Would you prefer, if available, an alternative to being a Republican or Democrat in the U.S.?

I’m not talking about third-parties in the U.S., but if a major overhaul of one of the parties took place. I guess what I’m asking is whether you feel at home in either the Democratic or Republican parties, and if not, do you find it frustrating how the country divides itself in these ways? Should either or both parties give way to a more representative platform, or do these platforms represent Americans well?
