I've found this website and have been watching the presidential approvals. I find it fascinating how similar they are to each other at the same time in their presidency.
Presidential approval comparison, at as close as possible to the same time period. Ford's numbers are ~4 months in (remember he started early). Johnson's has ~1 month additional seasoning for similar reasoning. Post WWII.

Post Nixon: George Bush Sr., Jimmy Carter are the high ends of the spectrum at this point in their Presidencies. Clinton the lowest, lower than similar Ford numbers interestingly. Its also interesting that pre nixon,. approval rates through Roosevelt (at least through 1941 the period of the run) are higher at all times at a statistcially significant level. Also interesting that the disapproval rates jump with Bill Clinton. Obama's numbers have dropped into post Nixon ranges at this point. Interesting that Obama and Bush have similar numbers especially the lack of unsure's. They were either loved or hated almost from the beginning of the Presidencies.
