FTP 6500 gtd ---AQ in the SB facing a raise and a reraise

[authority11]

CO is a complete donk and I know I'm ahead of his range. I planned on ISO'ing myself, but button beat me to it. I don't know what to think about button. He's probably been the most active at the table. Few hands before, he weakly reraised 2 limpers in LP with 10-2s, but I've also seen him show down JJ in a similar play.
