Whatever anyone says, impeachment is a political rather than a judicial process, and that is never more true than when the majority in the Senate is controlled by the president’s party. The Senate has the responsibility to decide whether a president should be removed from office, and with two-thirds requirement, it almost always requires that the president lose significant support from nominally aligned senators. As of today, Trump can lose the support of nineteen Republican senators before he crosses the threshold for removal.

That sounds impossible, and maybe it is. But if there is going to be a critical loss of support, it’s going to be a political decision by the senators that they cannot withstand an acquittal. How they calculate that will be partly individualized to their own particular circumstances. It will be partly an assessment of what is good for their party as a whole. And, yes, there is a component that involves what is best for the country.

The Kurdish fiasco is hurting Trump in each of these areas and making his removal from office much more possible than it otherwise would be. The problem is that things have turned to shit so quickly and so indisputably, and with such obviously negative consequences for the country, that the Republican senators are just as angry as the Democratic ones.

There are Republican senators who want Trump gone for this reason alone, and there is a real limit to how much shit they’re prepared to eat to pretend otherwise.
