Some snippets from the lyrics are as follows:
"Don’t need a Constitution or the rule of law,
we abuse our power using shock and awe.
Thousand page bills, see that’s the new norm,
nobody reads ‘em no more so we’ll get our reform.
Private sector takeover nearly complete,
got health and auto industries under our feet.
Regulate your light bulbs, your car and your pad,
listen up kids, government’s your new dad!"
It is from the Minnesota Majority who are a busy body of moralising conservatives and statists. In pointing the finger at their current enemy, Obama, they manage to capture the essence of government corruption. As with many conservatives the problems only "started" at the beginning of 2009.
In this clip Republican Michele Bachmann actually uses the phrase "gangster government" 1 minute and 40 seconds (1:40) into her speech. She can get on her high horse all she likes but she's still riding around in the same glass house. As above, she is so intent on damaging her enemy that she fails to notice the government wide applicability of her criticisms.
