At the six-month mark of his presidency, America is becoming less impressed with Donald Trump's performance as president. And this is how he compares to his predecessors:

No other president has received an approval rating as low as Trump in their first six months in office.

Trump has received a lower approval rating than Barack Obama, Bill Clinton, and Gerald Ford ever had in office.

Many former presidents received their highest approval ratings early on, some within the first 6 months.

It's not all bad: Trump has struggled to pass the key legislative items on his agenda, but he still has three and a half more years to push policy through and improve his ratings.
