Lots pressure from the GOP against the Federal Reserve? It’s all meaningless political talk for simpletons.
Push comes to shove, Wall Street and business groups want QE and an environment that is conducive to consumer spending and growth.
You’re both over- and under-estimating human rationality. On the one hand, a slowdown right now will make the sitting President look bad and make it less likely that anyone from his party will be elected in 2016. On the other hand, the wealthy profit most from a pump-and-dump, boom-and-bust cycle. Buy assets low, wait till the chumps start buying, driving prices up, dump the assets, repeat when the cycle repeats.
Wall Street loves volatility, whether they care to admit it or not. Especially if said volatility is somewhat predictable and can be timed well.
