We now know the cost of impeachment.

While Democrats were diverting the attention and energy of the entire country into a pointless trial that could not possibly have ended in anything other than President Donald Trump’s acquittal, the coronavirus pandemic was beginning in China and arriving in the United States.

The timeline of the two developments — impeachment and coronavirus — is shocking, and reveals the true cost of hyper-partisanship.

January 11: Chinese state media report the first known death from an illness originating in the Wuhan market.

Pelosi and House Democrats celebrate the “solemn” occasion with a signing ceremony, using commemorative pens. That same day, the first person with coronavirus in the United States arrives from China, where he had been in Wuhan.

For twenty days, from the day the first death from coronavirus was known, Democrats did nothing about it. They were too busy with the president’s impeachment trial — a trial Pelosi had delayed unnecessarily for several weeks.

To the extent that they commented on coronavirus at all, it was only to tear up the president’s remarks or to call him a racist. They told the nation that he, not coronavirus, was a threat to the national security of the United States.

In the midst of that all-consuming trial, it is remarkable Trump was able to do anything else at all. But he did, and one of the things he did was impose the China travel ban, just one day after the World Health Organization declared coronavirus a global health emergency, and the day before the first victim of the pandemic died outside China.

For his trouble, he was criticized by the World Health Organization and called “hysterical” by his future 2020 rival.

When Republicans warned Democrats that impeachment was a waste of time, a divisive partisan exercise, and a distraction from the real issues facing the country — a lesson Republicans learned the hard way, in Bill Clinton’s impeachment, 21 years before — Democrats ignored them.

Just a few weeks later, our divided leaders were taken by surprise by the pandemic, and bickered on cable news, asking why nothing was done sooner.

But we know why.
