Any trace of President Donald Trump’s impeachment has vanished from Capitol Hill, cable news and the campaign trail. And long gone is the pervasive sense of anxiety that once gripped vulnerable Democrats after their votes to impeach Trump, which they feared could cost them their seats and possibly control of the House.

Instead, the battle for Congress is more likely to be redefined by a highly infectious and mysterious virus that has spread into every state, pulverized the economy and thrust lawmakers into a crisis-governing mode unseen since the Great Depression.

“It’s always about, ‘What meeting are you going to on the virus?’ or, ‘What are you going to do on the virus bill?’” said Arizona Rep. Tom O’Halleran, one of the many Democrats in Trump-won districts who had been initially reluctant to pursue the president’s impeachment.

“I’ve been through a few decades, and I haven’t seen anything like this,” O’Halleran said of the outbreak, adding that the flood of phone calls he once got on impeachment have subsided.
