Republican lawmakers are receiving lots of advice–some from people sympathetic to the GOP, some less so–on the political dangers posed to them by the scandals engulfing the Obama administration.

It seems to me the proper approach is fairly obvious. Don’t get ahead of the facts. Don’t talk about impeachment or declare this or that scandal to be worse than Watergate (which placed the president at the center of a criminal conspiracy). Don’t allow opposition to President Obama to slip into hatred for him. Don’t come across as zealous partisans. And don’t become so obsessed by scandals that they set aside the hard and necessary work of recalibrating the GOP, which still faces significant problems in terms of its appeal to a changing electorate. Remember the words of Chekhov: “You don’t become a saint through other people’s sins.” 

At the same time, Republicans should of course pursue the scandals through the appropriate investigative channels, including congressional hearings. They have an obligation to do so in the name of the public interest. Those on the center-left and hard left who are urging Republicans to play down these scandals, in order to avoid a repeat of the Clinton-Lewinsky blowback, may have something other than the GOP’s interests in mind.

Perhaps it’s worth restating the obvious: Scandals and criminal investigations always harm an administration. Ask yourself this question: Do you think that Bill Clinton and Democrats, in looking back at the 1990s, are glad that Lewinsky scandal occurred? Of course not. The same goes for Watergate, Iran-Contra and countless minor ones. Political scandals are not good for presidencies–and they are not good for the country. But if they occur, they need to be pursued.

Republican lawmakers should approach the unfolding scandals in a manner that is sober, measured, purposeful, and rhetorically restrained. Follow the facts. Connect that dots when necessary–and don’t be afraid to say when the dots don’t connect. Resist the temptation to twist facts to fit into a preferred narrative.

All of this is easier to understand in theory than it is to execute in practice. But if Republicans do so, they’ll serve themselves, and the nation, well.
