Good luck with that.
Government is pretty much untouchable now. No one of any great importance gets held accountable anymore. Sure some lessers do and some others will fall on their sword for the team but mostly it's just what's called a "limited hang out" to make the people think something is being done until the next big story comes along to over write it and the people forget about it.
I wouldn't look for any real investigation into this.
I believe poncho is right.
It is possible that Obama could push the "stupid" American people over the line with another outstanding blunder like issuing an executive order granting amnesty to myriads of aliens hoping to capture their vote but thereby (IMO) destroying the credibility of the Democratic Party.
The problem with telling a lie so many times that people believe it (if indeed they do - "if you want to keep your doctor...") is that the liars themselves begin to believe it.
In addition and generally speaking these illegal aliens in mention have a stronger conservative set of values (apart from being survivor mode "undocumented aliens") and work ethic than their "liberators" and will turncoat on them in the voting booth.
Those who I know have the mindset of JFK who though himself a "liberal", made his famous "ask not what America can do for you, but what you can do for America" statement and then lowered the general income tax for most of the America people.
