Ace rag in the blinds - facing raise - line here?

[jackdaniels]

MP1 is typical ABC - so 88-AA, big Ace, 2 broadway here.
Button is a wild man. 90% of last 50 hands seen (crazy stuff like 62s at that). Any 2 here, but would definitly re-raise with a premium hand.

Preflop: Hero is BB with 3[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/heart.gif[/img].
2 folds, MP1 raises, 3 folds, Button calls, SB folds, Hero???

Is this an easy fold? What if I have A8o? How About A3s?
