PRESIDENT, CONGRESS AND WAR PRESIDENTIAL POWER OF UNILATERAL ACTION

Examples (as well as the above information on executive orders and military actions without declaration of war):

All but the last one was let stand. Why?

Another spatial model:

where C is the ideal point of a unicameral Congress, for example the position occupied by the median member when the issue involves a single dimension,
            P is the President's ideal point,
            and V is the point at which a presidential veto can be sustained. (Two thirds of the Congress is at V or to the left of it.)

If the president chooses P, his ideal point, he will probably be overridden by Congressional action.

Congress might choose C, but the president could veto that, and Congress could not override (because 2/3 of Congress agree only that policy should be no further towards P than V).

The point nearest to the president's ideal point that cannot be overridden is V, so the president will choose something near V.

Presumably, Clinton's action regarding gays in the military was beyond the veto pivot.
