Playing 100NL.

In late position.... SB.

Hole cards AKs.
UTG raises to $3.00 all call.
I figure I want to isolate so I raise to $9.00. EVERYBODY CALL!!!
WTF ... at 25 or 50 i would expect this but at 100?
Flop comes 10,10, Q. rainbow.
All check.
Turn 10. Mid bets 15. I fold.
River blank. showdown with 2. mid shows A, 1o.

My question should I have reraised preflop or just called?
