Mitch McConnell greatly damaged US democracy with quiet, chess-like moves | Gary Gerstle

While Trump's coup attempt may have failed, McConnell's own machinations have proven highly effective

The January 6 committee has now revealed how far Donald Trump was willing to go to prevent the peaceful and lawful transfer of power from his presidency to that of Joe Biden. Yet, his deadly serious attempt to upend American democracy also had a slapdash quality to it, reflecting Trump's own impulsive nature and his reliance on a group of schemers - Rudy Giuliani, Mike Flynn, Sidney Powell, Roger Stone and John Eastman among them - of limited ability. It is not entirely surprising that Trump's coup failed.

Another brazen GOP action, however, has succeeded - this one engineered by the Senate minority leader, Mitch McConnell, whose chess-like skills of political strategizing put to shame Trump's powerful but limited game of bluster and bullying. The act to which I refer is McConnell's theft of Barack Obama's 2016 appointment to the supreme court, a radical deed that has dimmed somewhat in public consciousness even as it proved crucial to fashioning a rightwing supreme court willing to overturn Roe v Wade and to destabilize American politics and American democracy in the process.
