There are 52 Americans who have it within their power to prove that dark assessment wrong. Really, it would take a subset of just three of those 52. With the 52-48 current party lineup in the U.S. Senate, a switch of three votes of conscience is all it would take to have this branch of government fulfill its checks-and-balances function.
With three votes, a Senate majority could issue subpoenas and compel sworn testimony from Administration officials. It could empower its own thorough investigation, even re-hiring Robert Mueller to lead it. It could compel Donald Trump to release the tax returns about which he is so evidently nervous. It could act as if America in fact possessed a system of rule-of-law, rather than whim-of-one-man.
Ben Sasse could be one of those three, if he were willing to back up his lectures and essays about ethical public life. Lindsey Graham could, since he and John McCain have kept making the case about Trump’s recklessness. Chuck Grassley, who would be 89 years old the next time he’d have to face the voters. Dean Heller, who is in trouble anyway in a state Hillary Clinton carried, and whom Trump demeans and insults. Rob Portman, who has served in “normal” Republican administrations and could ally himself with his state’s governor, John Kasich, as forces for a principled future GOP.
