But if Trump is impeached by the House and then acquitted in the Senate (as Bill Clinton was the last time we went through this), Democrats will have offered him a potent political weapon.
Green at any time can file articles of impeachment against Trump as a privileged resolution, which would trigger a two-day time clock in which the House has to consider the matter.
Ms Pelosi's comments are her first public stance against impeachment and come amid debate within the Democrats about how to handle Mr Trump's scandals.
But Pelosi has not yet found her footing, and one hopes she will soon enough.
Some Democrats are pushing back.
"Do we want to drag him down or do we want to lift people up?" Even if, as she may suspect, impeachment would be politically disadvantageous for Democrats, allowing Trump's clearly aberrant and destructive behavior to become normalized could threaten the future integrity of the presidency and of the country.
Meanwhile, some House progressives insist that the option of impeachment must be preserved.
The speaker's ability to keep the House Democratic Caucus-which spans the political spectrum from moderate liberals to Democratic Socialists-is also at play, the strategists said.

If that happens, however, Democrats would have the delightful choice of moving against Trump then or waiting to destroy him in the 2020 election after watching Republicans go after each other with tire irons. If so, let's litigate that, too. Impeachment hearings would be carried out to benefit the public and the country, and thus can't turn on projections of the ultimate outcome. Trump is enjoying economic good fortune (#ThanksObama) although it is fair to note that nearly all of the economic policies enacted by Trump and his party have hurt more Americans than they've helped.
