Horrible idea and bad idea. Lived under both. Both were sucky.
In any case the two-party system has taken us the same way the old Roman Green and Blue Teams were -- to general ignorance, rampant corruption and rah-rah know-nothingisms.
I disagree. The two party system is what built this country. I know that will not set well with you but it is the truth. And believe me you have no idea what "general ignorance, rampant corruption and rah-rah know-nothingisms" is if you think that is what you have here in the US.
Like most Americans, you have no idea how good it is here. That is not intended to be an insult. I hope you don't take it that way.
I've lived under rain, wind, snow, flood, fire, etc. etc. And blue skys, warm balmy weather. None of that was sucky. It was what it was.
You have lived in three places for what -- each not many years -- but you know all the tides and times of what is good and bad in politic, eh?
I think the US founding documents and theories are grand -- among the best things fashioned by the efforts of men. Yet in them -- no two party system. Washington was sickened by the party politics. He held a hope that the general public could rise above such insider-versus-outsider, blue team versus green team inanity as a subsitute for character, for integrity, for faithful, diligent, honest stewardship of our nation ruled according to our charter of it.
Washington seemed to favor a no-party system. I'm favoring a multi-party system -- for in such systems the political ideals are better carried -- a vote is for an idea, and not the current vote for for a person or a "party".
