From what I hear, it's difficult but doable if you try a few things:
1. Market other skills that compliment your law degree - if you have a MA in something or strong background in science and want to work in that legal area, show that off first.
2. If you have/had a good summer experience before you got your rank, get plenty of recs and show that the experience focused you on what you want to do/don't want to do with your law degree.
3. Bust your ass the remaining semesters.
I'm currently taking this advice (especially #3) and I believe it works out for the best in the end.
