Will Obama do what he said

Obama planned to get the troops out of Iraq, make a greener future, and help with the high tuition costs for colleges. What if he want to take action, but congress and or someone does not let him do what he wants. then it will make Obama look bad and do what he was elected to do. i think mostly half the [promises the president makes come true. Each presidents tries to fix the same problem that the other president tried to fix.
