Re-raise 99 out of big blind

Cash game... loose... lot's of 20 year old novices that over-value all hands and learned poker from watching Gus Hansen high-light reels.

For the first time in a long time at this Indian Casino I'm play super tight aggressive. Played two hands in about 2 1/2 hours and have had my $300 buyin blinded down to about $250.00

Button is a horrid player with about $70 who is looking to go all in ASAP.

3/5 blinds, everyone is opening for $15...

2 UTG opens for $15, 3 callers, button moves all in for $70.

I'm pretty sure my 99 is best here, and if I get any callers with over cards, a lot of their outs are probably counterfeited due to all the calling that occurred behind the originall raiser.

I re-raise all in for $180 more. Want to go heads up against the button Donkey... and honestly think I have the best hand right now?

Your thoughts?
