It’s extremely counter productive to attack your own party during a primary. Attack issues, is you must, but leave the politics of personal destruction out of it. Don’t do the Democrat’s job for them.
Every single Republican candidate, with the possible exception of Mitt Romney has something positive to bring to the table. If we emphasize the positives we can actually have more influence than we will have being constantly negative. It is possible to move the whole slate of candidates right with positive pressure.
No counter productive, are you Listening??? helping our MORTAL enemy build a DAMN Mosque!!
