Trump thinks the economy makes him impeachment-proof

President Trump has an impressive defense for why he shouldn’t be impeached: The economy is just too darn good!

“How do you impeach a President who has created the greatest Economy in the history of our Country?” he tweeted last weekend before listing other accomplishments that supposedly render him impeachment-proof. It’s one of several such recent remarks.

Of course, Trump suggests periodically that some good economic indicator insulates him from noneconomic failings (standard talking point: He can’t possibly be racist because unemployment for African Americans and Hispanics is low). So perhaps this latest development is unsurprising.

Still, the founders did not include a “strong economy” exemption for impeachment proceedings. If so, that would certainly be news to Bill Clinton.

In fact — aside from his ongoing, live-on-TV requests for even more foreign powers to investigate his political rivals — the sputtering economy could now be the single greatest threat to Trump’s ability to weather impeachment.

First things first: As I’ve noted before, presidents don’t control economies. Voters often attribute economic developments to the president’s wisdom (or folly), but big macro trends are largely determined by factors outside presidents’ power. That said, Trump likes to claim credit for the supposedly best-ever economy — even though on most major metrics, the overall economy is not appreciably different today than it was under his predecessor, Barack Obama.

If you look at, say, hiring or output growth, trends have been more or less the same until recently. In the first 33 months of Trump’s presidency, payroll growth averaged 190,000 jobs per month, not so different from the 226,000 per month in the last 33 months of Obama’s presidency. (The most recent jobs report, released Friday, showed September growth at 136,000.)

Trump did get a short-lived bump in gross domestic product growth in 2018, but that sugarhigh appears to have worn off. GDP growth in 2019 is now predicted to revert to roughly the same pace averaged in the several years preceding Trump’s tax cut.

Lately, more forward-looking indicators suggest things could soon get materially worse — foretelling a “grinding slowdown,” as Pantheon Macroeconomics chief economist Ian Shepherdson puts it, if not a full-blown recession.

This week, for instance, we learned that the manufacturing sector contracted for the second straight month, with the Institute for Supply Management’s manufacturing index notching its lowest reading since the Great Recession. Other metrics also imply that manufacturing is already in recession.

Business investment, which the tax cut was supposed to permanently increase, instead shrank in the most recent reading.

How much of this can you actually blame on Trump?

Like I said: He has limited control. To the extent that Trump does exert influence on the U.S. economy, though, he isn’t helping things.

Not through his trade wars, which are raising costs and uncertainty, and punishing farmers caught in the crossfire. Not through his administration’s conspicuous incompetence. Not through his attacks on Federal Reserve independence. And not by frittering away deficit-financed fiscal stimulus when the economy needed it least.

Perhaps Trump wasn’t completely wrong in identifying a link between the economy and impeachment: There is a political, if not exactly a constitutional, connection. So long as the public still views the economy (and Trump’s handling of it) favorably, members of his own party will continue to defend his most egregious transgressions. But if the economy continues to weaken — thanks in part to Trump’s own actions — GOP backbones might yet strengthen.
