You can straighten it by digging out the back side from the road. Then use the come-along to pull it straight. Dig out about 8" and it should be enough to level it. You may get it angled to one side but you can repeat the process. I would secure the come-along to my truck. Take your time or you will say:" I wish I hadn't dun dat". After you have it straight, pour concrete under it and up a couple of inches on the post. The wider the footer the least chance of doing it over. Good luck.
