[Buffy the Vampire Slayer] What was the Mayor's plan post Ascension?

So let's say graduation day comes and everything goes to plan.

Mayor Wilkins turns into a giant snake demon and devours everyone at graduation and maybe the rest of Sunnydale. 

What then?

What's he gonna do? Wander around SoCal wreaking havok until the army takes him out? He's a sixty foot long snake monster. It's not like he can hide or go back to doing human things.

Did he have a plan for after his ascension?

He may have been working off outdated information. “Ascend to become the demon Snakey McSnakerson and not even the mightiest of mortal powers may stand against you”, written in a time when the “mightiest of mortal powers” was, like, 60 guys with bronze spears and steel balls. 

He may have planned to head off to a hell dimension. 

Most likely, though, is what was hinted at: Both he and the previous dead McSnakerson got exploded/volcanoed before the transformation was complete, and if he’d only been given the time to chow down on a full graduating class he’d have become far more powerful - and then neither a library full of chemical fertiliser nor the mightiest of mortal powers (here represented by the US military) could have stopped him.
