I take David’s point below that Hillary’s sleazy tactics don’t justify Trump’s sleazy tactics. But so far what we know is that Don Jr. took a meeting with Russians that came to nothing. This was amateurish skullduggery. Hillary’s campaign used a cut-out to fund an effort to dig up dirt on Trump using Russian sources. This was professional skullduggery. And much more effective. It led to a salacious dossier that was spread to the press and appears to have been a key part of the case for surveilling a Trump campaign official. And yet the dossier is treated as no big deal, and even an important source of information, by the same press obsessed with the Trump Tower meeting. It’s understandable that people find this galling.
