I do not find this surprising at all:
Amid continued pessimism about the economy and direction of the country, 59 percent of Americans say they are disappointed in Mr. Obama's presidency (including 37 percent who are very disappointed); 40 percent are satisfied. Much of this discontent comes from Republicans and independents, but a quarter of Democrats express at least some disappointment.
Disappointment with Barack Obama's presidency has grown since the summer of 2012, and much of that rise has been among independents. Forty percent of independents say they are very disappointed today, up from 27 percent in August 2012.
