I wasn't trying so much to defend Bush -- he looked weak, and looking weak is what will cost him the election -- as to point out that it's easy for voters and politicians who don't have the responsibility for such decisions to run down his actions.
Generally speaking, politicians -- even those who make a lot of noise about no compromise and no backing off on other issues -- avoid tough cases like this when they are the ones who have answer for their decisions. It's not a sure thing that even whatever politician you like the best would act differently from Bush if they had the authority.
Then he uses his authority, places either Guard or private security indemnified by his authority around the building and MAKES the feds act on camera before the world and lets then deal with the fallout.
Let the feds try throwing a sitting Gov in a 10th Amendment dispute into prison.
MAKE THEM TRY. Thats being a leader. And he absolutely had the power to do it as Gov.
