Plenty of people have been admitted with poor UGPAs. Your particular issue is the LSAT score - not the UGPA. For many people who are out of school, there are often compelling reasons for arguing that the UGPA does not represent their potential. It is very difficult to argue that your LSAT score does not represent your potential - the LSAT is not a measure of your intelligence, but rather, a measure of preparation and dedication. This is the reason many people retake - to prove that they are diligent enough to do better.
A 145 simply isn't an adequate demonstration - this may sound brutal, but it's really just straightforward. With careful and consistent preparation, one should be able to do better. Especially with a poor GPA, the rest of your story has to compensate. You can make up for a poor GPA but you will be very hardpressed to makeup for a poor GPA AND a poor LSAT score.
