I don't normally listen to him for those very reasons.
I think what he's doing is sounding the alarm. I love Trump bringing Bambi to his knees, but what's being pointed out is important at this stage of the game, particularly since he is suddenly so popular amongst the GOP voters.
Trump supports national health care, gave to the most liberal causes and politicians (while supporting no conservatives or TEA party initiatives), speaks highly of Nancy Pelosi (wishing she had impeached Bush), gave to Harry Reid in 2010, was pro-abort all his life until he suddenly wants the GOP nomination, and simply is not a conservative at all.
There's a lot more, but the prime problem here is Trump being to the left of most of the RINO's we deplore and it's important that people understand that before the Trump train buys the nomination.
I'll support Trumps lambasting of Bambi, but be careful, the man isn't what he's pretending to be.
As for Sarah, she needs all the help she can get. If the media did its job, we wouldnt need help to expose this fraud. But the media covers for Obama, and we know how much the media ridicules Sarah, and for that reason people like Trump gives invaluable help in attacking Obama, which should be welcomed from conservatives.
And I wouldnt overstate Trump's appeal with GOP voters. He has high name recognition and is sucking up all the air, so that's bound to be reflected in polls. Just let the process take its course.
