Nancy Pelosi must have seen this coming.

The speaker of the House of Representatives said some time ago that she doesn’t favor impeaching Donald J. Trump. Then the special counsel, Robert Mueller, seemed to uphold Pelosi’s view that impeachment is a non-starter. He essentially cleared the president of colluding with the Russians who attacked our electoral system.

So now the task for Democrats has changed. They need to defeat Trump in November 2020’s presidential election. They might uncover more campaign grist from the congressional hearings they are planning in the weeks and months ahead. There seems to be plenty of campaign ammo to be loaded into their weapons.

For his part, Trump is preparing to batter the Democrats with Mueller’s findings. The “no collusion” mantra might as well become Trump’s 2020 re-election slogan. His dedicated base will glom on to it, citing what they insist was a “witch hunt” and an “illegal” investigation by the former director of the FBI; of course, it was neither a witch hunt or illegal.

Democrats must avoid overplaying their anger at Mueller’s findings. They spent a lot of time and emotional effort defending his integrity against the Trump attacks, which he mounted incessantly during the course of the past 22 months. They said Mueller’s integrity is impeccable; they praised his dedication and his thoroughness. So, he’s delivered them news they didn’t want to hear.

Democrats’ challenge now is finding a candidate who can stand up to Trump’s insults, his innuendo, his hideous rhetoric. They know what to expect, which I am quite certain will mirror what they heard from him on his way to election in 2016.

Impeachment now seems like a bridge too far.

As the speaker said, “He’s not just worth it.”
