I have fence posts which are in ground spikes,my problem is the 4x4s are leaning.. any suggestions on how to straighten them

How deep did you put your posts and what's the soil like in your area? Sounds like you did not pour concrete or gravel backfill, right?

The soil is very wet and clay... the posts are down about 3/4 of the way so that the posts are all level... I did not use concrete or gravel
