Whew!
That is a mouthful.
Altho I'd quibble a bit -- no 'idealism' here at all. In fact, 'Idealism' is what I'm fighting against.
I'm suggesting that politically 'conservative' means careful. Careful to only push for policies and solutions which are proven solid workable systemic solutions.
As Reagan pointed out in that speach, it is the 'ideologues' who are the problem with the R party. The folks on this thread who say, "if you don't believe x and y, you aren't one of us, regardless of your other views".
How do you implement oversight in a government without adding to said government?
By voting the bums out, of course.
My point is we need to vote for politicians who aggressively police their own party. When they don't, when they turn their backs on misdeeds by "their own", we vote them out.
Are you talking about accountability in a criminal sense, or as representatives of the people's will?
If the former, all that needs to be done is define what is unacceptable corruption and prosecute according to the law. But if you mean the latter, that could easily lead to government dependent on popular mandate for any action, and eventually government would devolve into rule by plebiscite. I don't see that as “careful.”
