President Trump tweeted Monday that support for impeachment is “dropping like a rock,” with his estimates of just how far down it has plummeted appearing way off but not entirely wrong.

The only poll taken so far after two weeks of televised impeachment hearings shows that 48% of registered voters favor impeaching or removing the president from office, with 45% opposed and 7% still undecided.

The same Yahoo News/You Gov poll points to independents being even more torn — with 40% in favor of ousting Trump and 23% not sure.

“It shows that many people are not paying attention,” veteran pollster John Zogby told the Herald. “It doesn’t have anything to do with putting the kids on the bus to school or getting to work on time.

“The Democrats,” he added, “have fallen into a trap. All the talk of impeachment drowns out the discussion of policy that matters to people.”

He also said Democrats risk appearing as if they are “obsessed” with removing Trump from office instead of backing a candidate who can take him on in the general election.

Most of the other polls show strong support for and against impeachment along party lines — with 83% of Democrats all for it and 83% of Republicans dead set against it.

A Real Clear Politics average has 48% of polls calling for impeachment and 46% against.

Meanwhile, a federal judge Monday ordered former White House counsel Donald McGahn to appear before Congress in a setback to Trump’s effort to keep his top aides from testifying.

The outcome could lead to renewed efforts by House Democrats to compel testimony from other high-ranking officials, including former national security adviser John Bolton.

Judge Ketanji Brown Jackson issued the ruling on McGahn’s appearance on Monday in a lawsuit filed by the House Judiciary Committee.

McGahn was a star witness in special counsel Robert Mueller’s investigation, and Democrats wanted to question McGahn about possible obstruction of justice by Trump. That was months before the House started an impeachment inquiry into Trump’s effort to get Ukraine to announce an investigation of former Vice President Joe Biden.
