Bernie Sanders is polling way behind Hillary and until the polls show him much stronger the GOP is not going to attack him. They have no reason to. Notice that all the attack ads and OP's from right wing resources are against Hillary.

I'd think it odd that wingnuts would be able to control their frothing as concerns Sanders, but it's not improbable I guess.

I'd do it, but I'm on.my tablet and the search function doesn't even appear on my screen

Just spent my last five bucks to have the Bentley trunk key re-chromed.

Maybe someone else can help.

I couldn't find anything bad against him but I did find this awesome "404 Not Found" response, from Bernie himself, in case you lose your way at BernieSanders.com:

and if he ever shows up, they're confident they can torpedo his hopes with one word, "socialist."

The major news media are studiously ignoring him.

He's not polling all that well in national polls, although he's doing well on the internet and his crowds have often been very large.

Besides, they're spending all their time talking about Clinton's hair, pantsuits, and speaking voice.
