President Trump's approval ratings have not only hit a new low but have fallen below both Bill Clinton and Gerald Ford's worst-ever numbers during their presidencies, Gallup said Monday.

Trump's approval numbers dropped to 36 percent over March 24-26, a time period that includes his failure to get Congress to pass legislation to repeal and replace Obamacare.

According to Gallup, Clinton's all-time low was 37 percent in 1993. Ford hit his 37 percent low point in January and March of 1975.

Former President Obama's hit his all-time Gallup low of 38 percent in 2011 and 2014.

Other presidents, according to Gallup, that had worse all-time lows than Trump: George W. Bush hit 25 percent, George H.W. Bush hit 29 percent, Ronald Reagan hit 35 percent, Jimmy Carter hit 28 percent, Richard Nixon hit 24 percent, Lyndon Johnson hit 35 percent and Harry Truman hit 22 percent.

Gallup cautioned in an analysis that these ratings "are fluid, and all presidents have seen both upward and downward swings in their ratings at various points in their administrations — a historical precedent indicating Trump's approval could drop further or recover in the weeks and months ahead."

"An encouraging sign for Trump, perhaps, is that all presidents whose ratings fell below 36% — with the exception of Nixon — saw their ratings improve thereafter," the polling outfit said.
