Crazy?"
Yeah no doubt.
Politically crazy, too.
Hence his choice of victim.
Would that mean the fort hood shooter was a muslim terrorist hense his choice of victims?
The AZ shooter was crazy and so has been the Left and MSM's reaction.
This whole reaction by the Left and the MSM over the last few days has been of the "tin-foil" hat variety.
In connection with the their
"Palin Derangement Syndrome"
this has really brought out the "loonies' and the worst from the Left, as evidenced even by their postings.
For example of more Left loonies see:
Tucson Shooting Victim Arrested at Town Hall Meeting
Even liberal NYT's columnist blasts Left for “witch hunt” after Tucson shootingIt’s not Ross Douthat or David Brooks, either, but
Charles Blow — the same writer who once called black Tea Party activists a “
political minstrel show.” Blow admits that the temptation to lay the blame for the shootings in Tucson on the Right was strong, but that in doing so, and in insisting on sticking with the attacks after all the evidence showed that the shooter was an apolitical lunatic, the Left have adopted an “any means necessary” approach that will destroy their credibility

I BEG of you my comrades, DO NOT TAKE OFF YOUR TIN FOIL HAT!
If you do then Sarah Palin or Tea Party People will get into your head and cause you to do horrible things and provoke you to do violence.

When you get down to it, this has been the lame argument by the Left and the MSM for the last few days.
The US majority is not buying it and even some on the Left are starting to pull away from their loony, radical members on the Left.
You see some of the more rational Left here, trying to move the "goal posts"; change the subject matter or back peddle to a different issue-
because they know it's a losing line of argument and makes them look nutty.
One has to wonder how many of these fringe Leftists are "911 Truthers" as well ?
