There are a number of reasons why Trump’s approval rating dipped, but the most likely ones are the largest ones:
- The complete and utter failure of TrumpCare.
- A continued investigations into Trump’s ties to Russiathat could lead to Trump being indicted for treason.
- Trump’s likely cemented reputation as a serial liar who doesn’t care about average Americans.
There could be other reasons, but these are the big ones.
