The stabilization comes from the tidal interaction between the Earth and the Moon.
Explanation:
The same tidal interaction that makes high and low tides line up closely with the Moon, does the same thing with the bulge at our Equator; in effect the bulge is like a big high tide that tends to favor facing the biggest tidal force -- which is from the Moon. The Equator is pulled close to the plane of the Moon's orbit, and the poles follow suit.
