Rush Limbaugh producer of death threats?

I have an in law in the secret service who says death threats on the prez are off the charts with Rush's noise and protest. Why are people the effect of someone that only incites fear and hate and produces no solutions that anyone can use? Why haven't the republicans drawn up some stimulus package or offered some solutions to the situations the Republicans have put us in today? Is anyone else out there amazed with the current scene in media and Washington?
