MOLLY BALL: Nancy Pelosi Doesn’t Want to Talk About Impeachment. The Democrats May Not Be Able to Resist It.

Democrats control the House, and about three-quarters of their voters favor impeachment. A well-funded grassroots movement is mounting an aggressive campaign to pressure wavering lawmakers. Multiple investigations into the President, his business and his Administration are under way. The one led by special counsel Robert Mueller may conclude any day, but no matter what Mueller finds, many Democrats in Congress believe there’s already ample evidence that Trump has committed crimes and proven himself unfit to serve. These lawmakers see a moral imperative to seek the remedy prescribed by the Constitution.

More than a quarter of the 235 Democrats in the House have already expressed support for Trump’s impeachment. Virtually everyone else is taking a “wait for Mueller” approach. But no one is ruling it out. And to many, the prospect of opening impeachment proceedings against Trump seems inevitable. “It’s not a matter of whether, it’s a matter of when,” as Representative John Yarmuth of Kentucky told CNN on March 12.

All they have to do is not act crazy… and you know the rest.
