"Trow da bums out!" A nice idea, but for all purposes, practically impossible, at least by peacable means. History bears this out.
The strength of this country, the fact that it hasn't experienced a truly violent transition of administration with exception of the Lincoln presidency of 1860, is the willingness of both sides to participate peacefully in the activity of governance, to work with what they have, so to speak. Self-serving politicians always will exist, as will selfless ones. The point is to foster and nourish a system whereby the selfless ones outnumber and outmaneuver the self-serving ones in the interest of the public good.
People will disagree on political, moral, cultural, religious, etc. issues for a long time to come, probably forever. Replacing in its entirety the current slate of political office holders, liberal and conservative alike, does relatively little to alleviate or transcend those tensions. Replace them all, but with who? Liberals and conservatives, and people in the middle, and people on the edges of political thought and American culture all will continue to disagree vociferously on this.
To preserve the strength of this country, people on both sides need to rediscover how to work with what they have, to work together for improvement rather than to rue their current representatives and wish for the good old days, which BTW never existed, at least not in the form that most people believe them to have existed.
I've offered my olive branch ... anybody else?
I don't think that anybody here really wants to start advocating non-peacable means to "wipe the slate clean", do they?
If so, I'm outta here ...
