To my knowledge...
Bowser has hated every administration in the past 50 years.
Bush II- hates him
Clinton- hated him
Bush I- hated him
Reagan- hated him
Carter- not sure how he felt about him
Nixon- hated him
Johnson- hated him
Kennedy- maybe Kennedy was before the great warping
If Kerry had been elected, I'll bet Bowser would be hating him by now.
