I agree that evil is power-lust, but that it is not power, itself -- but Satan was supernatural and, if being friggin' supernatural isn't sufficient for calling something powerful, then what is???
As it stands, your otherwise-unqualified quote can mean only one of the following things:
A) Saul Alinsky, and the commie bastards who revere him, aren't evil -- because they stand in awe of Satan, and Satan is a powerful figure, but evil isn't powerful
B) Satan, himself, even though supernatural, was not evil -- at least not if he had a powerful sword! -- because evil is impotent, and supernatural beings armed with swords can do a lot of real damage (which is the opposite of impotency).
C) Saul Alinsky and Barack Obama are the kind of guys who would be found at a party, sitting in the corner, drinking Coca-Cola out of bottles.
