Drop the second major if you're sure you want to do law. GPA and LSAT are 90% of the process. Everything else is marginal at best (unless you're URM, in which case numbers don't really matter).

Oh yea...you're delicious and lean, but unsustainable and not to be consumed daily.
I agree that GPA and LSAT are 90%, so if one major is keeping your GPA down, drop it immediately. Econ is certainly helpful, but if you can't stay above a 3.5 because of it, it's not doing you any good. I majored in English, maintained a 3.9, and got into Harvard Law School. The major doesn't matter. Your GPA is more important.
