House Speaker Nancy Pelosi doesn’t know how to read her audience.

The California Democrat has spent the past few weeks attempting to convince the public that impeachment is serious and necessary. The GOP, of course, disagrees, so she’s made a point of ridiculing Republican leadership for turning the Senate’s impeachment trial into a political “sham.” But public opinion is still largely divided, and Pelosi has failed to convince the other half of the electorate that she has the better argument.
