I'm not sure either party can govern effectively when they are in a political bubble. It seems that both ideas have good sides and the best governments are the (rare) ones where multiple parties have power and compromise occurs.

However in America I only get to vote for one of two sides and I still think mine is the lesser of two evils.

It'd be really nice if America could crack the two party system that's so heavily entrenched but... that'll only happen with the cooperation of those parties which have no motivation to do so - other than silly things like "democratic ideals" and "making a fair and open society"

If I can identify some other city that has been under liberal democrat control for decades and isn't dysfunctional, then it's not irrational for me maintain my ideology while asking for better from this one.
