Trying to find a correlation between how the actual economy is doing and the current president is in my opinion a foolish endeavor. It takes way too long for a policy change to actually impact the economy and on top of that it's pretty much impossible to isolate the cause of the economic change. How the market reacts in the short term is even less relevant since it really only says how a certain group of people likes the change and isn't necessarily related at all to how the economy will nee impacted by the change.
Every time a president claims economic growth to be because of them they reveal themselves to either be a liar or a fool.
