How to respond to a probable bluff raise on flop

[gomberg]

PP 5-10 NL. Table is playing aggro. I have $700.

Villain has me covered and has been calling raises w/ position and using it nicely.

I open raise to $35 from MP w/ JJ, villain calls in late, one of the blinds call.

Flop: TT4. checked to me, I bet out $100, villain raises to $250, blind folds, actions to me...

My read is that he's bluffing. He'll call the raise preflop w/ any two there. He's been bluff raising flops (unless he was rushing or something) for the past 1/2 hour or so. I thought about calling or pushing.... Thoughts? Is this an obvious push?
