One thing i have done to help with this situation is to over seed the clover with brassicas and turnips in late august or early september. As long as you get enough rain and the temps stay reasonably cool it works out great. I mow my clover really short and lightly disk it. I then just broadcast spread my brassica seed on top after fertilizing and limeing. The mowing and fertilizing promotes lots of regrowth for the clover which really ramp up the attractivness to the deer and then once the clover starts to go dormant after several frosts the brassicas are starting to sweeten and become very attractive. This way you have one food plot that is attractive nearly all season and you can do the same thing several years in a row and still have a lush clover plot throughout the spring and summer.
