Half-True
Trump
"I’ve had tremendous Republican support. I have a 90% — 94% approval rating, as of this morning, in the Republican Party. That’s an all-time record."    

Donald Trump on Tuesday, June 4th, 2019 in a press conference in London

Republicans support Donald Trump, but not as much as he said

President Donald Trump has a commanding hold on Republican voters, but it isn’t as high as he says.

In a news conference with British Prime Minister Theresa May, a reporter asked Trump what he thought of Republican lawmakers who threatened to block his planned tariffs against Mexico.

"I think if they do, it’s foolish," Trump said June 4. "I’ve had tremendous Republican support. I have a 90% — 94% approval rating, as of this morning, in the Republican Party. That’s an all-time record. Can you believe that? Isn’t that something? I love records."

Trump does enjoy strong support among Republican voters. But no public poll backs up the stellar performance he touted. We emailed the White House to point us to the poll Trump relied on. We did not hear back.

Looking at support among Republican voters, Trump’s highest number in the latest polls is 87% from Gallup. CNN comes in second at 86%. The other four are lower.

All polls are based on surveys done at the end of May. No margin of error, among the polls that provide them, would be large enough to deliver the 94% that Trump claimed.

Setting no records

Trump’s approval among Republicans has generally held in the mid-to-high 80s, which would qualify as robust. Gallup clocked in a slightly higher number of 90% in March and April. That sort of shift is within the normal variation in polling.

We checked out whether Trump’s Republican approval was at an all-time high, both at this point in comparable tenures or all-time, as he said.

At this point in his administration (around the 860-day mark), Trump’s approval comes in a bit behind George W. Bush, who held a 94% approval rating within his party, as did his father George H.W. Bush. Ronald Reagan and Richard Nixon brought up the rear, getting the nod from just 79% of Republican voters in May of their third year in office. Here’s the full picture, going back to Dwight Eisenhower.

Trump once claimed that he had the highest polling numbers "in the history of the Republican Party. That includes Honest Abe Lincoln and Ronald Reagan." We rated that False. Not only have other presidents in the recent past enjoyed higher numbers, but there is no data from Lincoln’s time. That is pure invention.

For real record-setting, look to George W. Bush who, according to Gallup, won approval from 99% of Republicans in the month after the Sept. 11 terrorist attacks.

Our ruling

Trump said, "I’ve had tremendous Republican support. I have a 90% — 94% approval rating, as of this morning, in the Republican Party. That’s an all-time record."

While his numbers hold steady in the mid-to-high 80s, no poll puts him at 94%. Nor did the White House point to a poll with that level of support. Still, 87% or 89% approval is a strong showing.

Where Trump went overboard was in saying he had set some kind of all-time record. That didn’t happen.

The statement as a whole is partially accurate, so we rate it Half True.
