When Republicans are complaining about a thing, it's never really about the thing itself for them. They see politics and I guess all of life as a game, a debating game, where they analyse their opponents and see everything different from the norm as an opportunity to attack their opponents with. While to normal people taking a risk with anything (from fashion choices to supporting something ahead of the bandwagon) would be celebrated, they pounce on it. If it's something actually wrong, they enlarge it beyond recognition.

It's not even about them not doing the same thing. It's still that game: if your opponent has an opportunity to attack you back on the same thing, but doesn't, they don't see their own failing, but their opponent's weakness.

This is even true with Clinton's email server: they weren't phased one bit when it came out they did the same thing, because that never was the issue.

So don't debate back on the issue. Ignore. Don't point out the hypocrisy, they don't care. Don't reply. Counter with things they do wrong, for there are many.
