beleaguered
harried
harrassed
...the implication here being the guy is decent at his core, but is set upon by outside forces wanting to tear him down for his mistakes/missteps.
britneyized
...when you have everything in the world going for you, youth, fame, money, 'talent,' and wind up pissing it all away over some sleazy lothario gold digging poseur fool.
disenfranchised
censored (not sure if this is the correct spelling for when a president is officially chastised. i'm thinking it's not. 'censured'?)
...i think both of these basically amount to being caught doing some kind of wrong, yet not so horrible an offense as to be excised from office... though that won't stop people from viewing him with a squinty eye from now on. maybe 'disenfranchised' doesn't apply as much or has a different meaning? i'm thinking more about how that word connotes to me, though it may technically mean a permanent removal, i'm suddenly not sure once i actually think about it.
dismatic
...a word i just made up to mean actively screwing himself up despite his intentions, to where a current review would result in a dismal performance evaluation.
castigated
...punished in order to be corrected. this doesn't apply so much to a president as it would, for example, apply to an employee to be susupended without pay for being late too many times. while it does mean also to punish or reprimand severely, censure is a much more appropriate choice for a president that means about the same thing (though being censured doesn't mean there's any real punishment ~ you can't suspend a president, after all. it does, however, leave a bruise on his legacy. that is, there's also going to be an asterick associated with the name.)
