The first day of the Senate impeachment trial of Donald Trump was a perfect microcosm of the country’s partisan divide and what’s at stake in a post-Trump America. On one side are dedicated lawmakers trying to cobble a broken nation back together, taking their roles seriously and clearly acting with heavy hearts in the wake of a violent insurrection. On the other are those who believe these hearings are not in their party’s interests, and are willing, again, to put party over country while they demand that a fractured democracy move on without tending to its wounds.
