PP $5 R+A Final two tables...small stack CALLs

Greetings all. Sometime reader, first time poster.

It's a PP $5 R+A, down from 1700 or so players to 12 on two tables.

Read on CO was 10% bluff, 40% mid-pockets, 40% AK/AQ/AJ, 10% high pockets.

CO had been raising in position 2.5 BB or so with some regularity.

I'd be very interested in hearing feedback on my choice to call as opposed to push. My pre-flop intention was to try a stop and go as I suspected that a push here would have been called regardless.

Or...Did simply I mangle this? All feedback greatly appreciated.

Push preflop, this isn't a time for a stop and go because you probably have a pretty big edge against this guys range of hands

So...does this mean that I assigned him too small a percentage for bluff? I assumed that even as active as he was, he must at least be raising with small pockets or unsuited high cards. I don't have a big edge against the majority of those holdings and was hoping to avoid a coinflip.

Believe me, I'm looking for reasons to push this preflop - and again, I'd decided preflop that all my money was going in on the flop - so either way my money is going in. Doesn't it seem like it would be +EV to at least attempt to get him to laydown on the flop?

Am I severely underestimating the likelihood that he would fold to a preflop reraise all-in?

Am I severely underestimating the likelihood that I am a big favorite preflop?

Thanks for the response,
