Prez has the authority to act as a monarch, by design when the need arises: and I think the need has arisen.
To some extent he has that power, in an emergency he should use it as well. As in an attack-counterattack scenario. But this, that aint. Commin up on two years since we were attacked, we went in and bombed Afganistan back to the precambrian and that should be the extent of the prez's Kingly powers IMO.
If we're going to allow this then we will esentially allow anything becuse there is no emergengy here, no need for Kingly authority. Plenty of time to deliberate, as it was intended.
