cash game antics

[Tea_Bagger]

Cash game. $5 buy-in (so everyone is playing pretty loose). It's getting late and there's been talk about calling it a night. I'm on the button with 10 10. 6 handed with 1 limper in front of me. I raise to 4x BB (BB is $.20) and SB pushes all in. I'm not worried about him at all as he's been pushing with suited connectors and worse (K5, J7, etc). However, the limper calls and its $10 back to me. I'm getting 3-1 with basically dead money from the SB. I'm only worried about the original limper, but he could easily be calling with AK, AQ, AJ, or even A10, KQ, KJ (these cash games are a joke...). What's my play? Fold/Call?

BTW, they both have roughly $10 while I'm up to $20 on my original buy-in. Should this factor into my decision?
