First Term Presidents Expect too much Credit for their first year

I ignore ALL presidents who claim any economic credit (or receive blame) in their first year.

A president doesn't submit his own first budget until later in the year (~October) of his inauguration year. So, it isn't even logical to think a president's inauguration year has anything to do with economic improvement or decline.

Furthermore, the recent tax cuts (for Trump) that just kicked in January 2018 and won't actually be realized/recognized until February at the earliest ... so there really isn't any way to tie cause-and-effect except to make a general statement about people possibly behaving differently based on expected future tax savings.

Which, even if valid, is not measurable and therefore isn't something that could be touted if one were being honest. But that won't keep shameless Trump from taking credit.
