You much watch what they do.. and react to it..
Is Bush a tool or a believer?.. Who cares?..
Sometimes he is one sometimes he is the other..
YOUR reaction is what counts..
Even if you hated his guts in every other regard, your insistence on arguing that he did no good in any area of his Presidency puts you in the same category as any leftist who does the same thing as you are doing - i.e. the Alan Graysons and Barack Obamas of the world.
Your ideology may be better than theirs, but your thought process is the same. Irrational.
btw, I've spent a lot of hours making a great deal of effort (in the REAL world) to rid the Republican party of leftists. I would wager that you haven't done anything of the sort, though it would give you more credibility if you actually had.
