Maned,
The "utter destruction of small businesses" would happen how exactly?
It looks like the walmarts, chain shops, and chain restaurants are doing a pretty solid job of destroying small businesses of all sorts without an Obama tax policy change. What is it specifically about Obama as president that's going to add fuel to the fire?
To be honest, the teeth gnashing about how destructive Obama will be is only going to help the welfare state supporters-when the reality is that none of these dire predictions come true, the critics of the Obama plans will be discredited.
Over-hyping the evils of Obama is one of the best things that could happen to Obama at this stage: now that he's near certain to win, any beneficial effect to the economy as a result of his first term will look like a big victory. So in a sense, what the Obama apocalypse predictions are doing now is helping to give Obama term number 2, on top of term number 1.
Measured, accurate, and issues based criticism is what he is vulnerable to at this point. The right's failure to do that, instead going with sensationalism, predictions of doom, and "who is Obama?" is directly responsible for its abysmal polling.
