Here's a very simple observation.
All the democratic programs increase, at least from the Bush years, the involvement of government and the power of government.
Health care reform, for one example, has at least a huge new amount of government control over private enterprise. It may involve a public option, basically a government run insurance company. It may involve single payer, making the government the sole insurer and responsible party for paying for your care.
Given that, why would ANY democrat say that politicians can't be trusted to do the right thing?
If you sincerely believe that the first, and preferred resort, of a politician is by nature to screw you, you don't want that program.
If you say that Obama is in the pocket of insurance companies and is simply lying to us, then you don't want that program.
If you say that only constant kicking and screaming keeps the democrats on the path of reform, then what happens when the republicans (or some other conservative party) comes back into power, in ten or twenty years? A party that does NOT say it wanted the programs. You don't want the program if it just becomes something for the republicans to destroy.
If you really think the WH CoS is a mole who is able to subvert all to his whim, you don't want these programs.
In other words, the constant attempt to gin up levels of noise with articulated and open distrust and accusations of corruption of all politicians will work against convincing the larger public that the government, run as it is by politicians, should be given responsibility for new programs.
Tactically, getting people howling mad at perfidy, even of those who openly espouse your positions, doubting their words and accusing them of corruption, may make sense. Strategically, it's a loser.
It's impossible to scream at pols every day, and everyone knows it: as matters become bureaucratized and routine, we don't get to see them every day. If we can't trust the pols, we can't trust the government. If we can't trust the government, the programs will be expensive failures.
I'm going to assume that democrats, just because they are democrats, really do trust the government, and the tactics of distrust and cynicims are just tactics. They aren't good ones. They carry with them seeds of ultimate failure.
So tone it down to, say, "trust but verify". It was good enough for a nuclear USSR, so it's good enough for Obama.
