Clinton could have done anything and he would have been golden. He had the tech boom behind him.
But to answer the question, Barak won't raise taxes on anyone as long as the economy is in the shitter. He is not stupid.
Afterwords, the raise on the wealthy will cut employment somewhat, just as raising the minimum wage does. Its basic econ 101 common sense. The question to ask is whether other things in the economy more than make up for this. If Barak goes through with his Keynesian infrastructure spending, that will definitely help the economy and employment short term, just as it did for FDR. Need higher taxes for this, but no way would the cost be covered, so in the long run its usually not something we do here.
Who knows long term, but you have to admit, Obama has great timing. The economy will be better in 4 years no matter what he does. He is coming in at or near a low. He will look golden and have 8 years easy I bet.
