The idea that what a candidate promises and what a President knows can happen are the same thing.
The idea that Obama devises and orchestrates everything personally (he doesn't).
The idea that Obama is aware of everything that goes on in every division (he doesn't, it became obvious years ago that one hand does not always know what the other is doing).
The idea that the rest of the government is powerless to stop him (they're not).
The idea that it is acceptable to build a case against
anyone using half truths and out of context comments (it's not).
The idea that a person (or persons) should maintain their initial stance on something no matter what, even though situations change and new information is learned which might render that stance irrelevant or inadequate.
Obama has had his share of missteps, just as every President has. He is not the greatest we've had, but I don't know that he is the worst. Yet. As you say, we will learn much more once he is out and his memoirs are released (ever read Reagans diary? Specifically the details on Iran/Contra? Talk about admission to illegal and impeachable actions...). Still, our government does not operate upon the whims on one single man.
What bothers me most about the bullshit is not who it is aimed at (that is the least bothersome actually), it is how many people jump on that wagon and accept/believe it so passionately. If they are that easily coerced into giving validity to what essentially are lies, and not at all willing to spend any amount of time or rational thought as to what is actually going on, what kind of person are they going to vote for next? More to the point: if we have any hope of having any kind of respectable leadership, we need to hold our own selves to a higher standard. We keep getting crummy presidents and lame ass representatives because we willingly keep sucking down bad information and applying it to our voting decisions. If you are one of the people that perpetuates that bad information, you are just as much to blame as the people that create it.
