Via Pravda on the Potomac, we get a fresh sample:

President Bush's troubles with congressional Republicans, which erupted during the backlash to the Dubai seaport deal, are rooted in policy frustrations and personal resentments that GOP lawmakers say stretch back to the opening days of the administration.

What Bush is facing now, beyond just election-year jitters by legislators eyeing his depressed approval ratings, is a rebellion that has been brewing since the days when he looked invincible, say many lawmakers and strategists.

I know this story practically writes itself, so our lazy scribes like to run with it, but this just pins my bogometer. It's very simple:
When the Republicans call Bush on his lawbreaking, instead of rewriting to laws to retrospectively and putatively "legalize" what he's done, I'll call that a rebellion.

Until I see that, this is nothing but election year posturing. So far, Bush's Dubai fiasco has "worked out well" for the Republicans--it's giving them the cover they need to seperate themselves from an extremely unpopular "President."
