Ever since Karl Rove's involvement with the GOP began, there's a trend in campaigns he touches where the candidates deny or denigrate a negative issue within their own policies or ranks by projecting it onto their opponents.
So when Romney/Ryan/Republicans talk about class warfare, they're merely attempting to move that failure from their brand and rebrand it Democratic. Sadly, it works when you also own a media outlet watched by the vast majority of your party's supporters. But to those not so close to the trees that they can still see the forest, it's a puerile tactic.
The same goes for wealth redistribution. While it's a conservative ideal to move wealth upward, they fear any downward redistribution, even when that redistribution is simply paying the middle and working classes living wages.
Their belief is that by being proactive rather than reactive, they control the ball and hence the game. But telling a lie before the fact doesn't exonerate the liar, it merely doubles down the offense by virtue of premeditation.
