Check for a draw when your car is sitting. Gary

a draw across the battery post?

90% (a number I made up) of electrical problems are ground issues. You stated you have good connections, might recheck them just to be sure.

Disconnect 1 battery cable and check for current between the post you just took it off and the cable. It should have none. That is what was suggested in post #2.
When was the last time you had the starter motor apart and serviced?

Check and clean all your grounds. Put di-electric (can get it at napa) grease on all the ground points after you clean them to help keep them clean and working properly.

You could try and charge the battery first then try

Check battery voltage first thing in the morning before you start it. Should be at least 6.3 or so. Then check it while cranking. Off the top of my head, should be about 5 v.
