Under a government where both parties, no matter how much they quibble with one another, both approve of wiretapping (listening to celphones, monitoring online communications) citizens with no real warrant, maintaining a secret and unchallengeable "no-fly" list and torture as a means of interrogation, remaining loyal to either party is just letting them play you for a fool.
The actual government in this country is an oligarchy of influential and (eventually if not to begin with) wealthy persons, membership in which is largely closed to most citizens. They may squabble over the fine points but they close ranks against any outside challenge. All they're in it for is themselves,, no matter how much they natter on about public service, posterity or the beleaguered taxpayer. If you get in their way, they will grind you up but in general, they regard you the way an old-fashioned farmer regards barn cats: disposable conveniences. Get inconvenient and... Well. There are plenty more.
