CuriousJockAZ saidI suspect the first thing that would happen if Obama made such an announcement is that the stock market would see one of the biggest rallies in history.
I think there would be a rally, but I doubt it would be sustained because his bowing out would not resolve issues having a major impact on business growth such as Obamacare and the massive, new anti-business regulations, especially from the EPA. If he bowed out and Hillary ran, she would probably increase the chances of the Democrats holding onto the WH and Senate. While she might rein in the EPA to some extent, it is doubtful she would support repeal of Obamacare, and we would be dependent on the Supreme Court decision.
Right now I think businesses are hopeful that Republicans will take the WH and Senate, removing the influence of the progressive wing of the Democratic Party. Yesterday I had a long conversation with an owner of several businesses, including a small one with approx 80 employees. This business is ripe for expansion. He would like to double it. He said the business is there and he has the cash available to expand, but he won't right now because of the uncertainties and known higher costs associated with Obamacare and the flood of regulations. He said even keeping the current health plans is not possible because Obamacare requires all plans include features that most of his employees neither need nor want. I think he mentioned the features include fertility counseling, and the like, but I'm not completely sure on this. He said the smartest thing he could do now is create the new capacity in China, and even consider relocating existing capacity to China, but he doesn't want to do that out of his concern for his current employees and patriotism. He is just hopeful the election results in a pro-business change.
