Joseph: I stand corrected. Obama did indeed give his Nobel Prize winnings away, but that $1.4 million is not listed as declared income. Based on that sum alone, the $5.5 million the Obamas have earned, they remain less charitable than their predecessors. This only reiterates the point that it’s difficult to give money one has earned away. Though, I’m sure, the administration would argue President Obama earned the Nobel Prize, too.
But, you’re right, earned or not, the total sum does make him more charitable than Bush.
