INVESTI-GATE….Republicans are already raising money from their true-believer base by warning them that a Democratic victory in November will mean nothing but endless investigations of the president. The mainstream press has picked up on this theme too. So does that mean Democrats should avoid the subject for fear of looking hyperpartisan? I think Zack Roth gets the answer right in “Investi-Gate,” in the June issue of the Monthly:

Democrats might wish they could avoid talking about their investigative plans. But if they do, the press and the GOP will raise the issue for them, and they’ll frame it around the prospect of impeachment. So Democrats might as well meet the challenge head on, and spend the summer making their case. Of course we’ll vigorously investigate the administration if we win, they should say. And we’ll do so the same way previous Democratic Congresses have investigated GOP presidents: shoulder-to-shoulder with honest Republican lawmakers willing to put country before party. The fact that the current GOP leadership chose to abandon the great American tradition of bipartisan Congressional oversight is no reason Democrats have to follow suit. Instead, they should embrace that tradition, with the faith that if they do, the president will get the legacy he deserves.

Read the whole thing. Done right, a promise of oversight can be a powerful campaign issue. Done timidly, though, it’s a sure loser.
