I've had and still have my doubts about the ideological reliability of Donald Trump. But I cannot deny he is a scrappy fighter. Today's entry is a new ad entitled "Having trouble sleeping at night?" showing a woman asleep during a Jeb Bush speech and concluding with "Jeb--for all your sleeping needs". (Although, if I may shamelessly do so, I'd like to plug my own parody version of the speech with enhanced snoring and yawns).

Trump isn't even responding to attacks from Jeb. There are no substantive attacks from Jeb. His fleet was sunk at Midway. Trump is on the offensive, and attacking not just the policies of Bush but his personality.

I think that's important. While I think the best kind of contrast ads are those that show the problems with an opposing candidate's views, we've never had a Republican candidate who engaged his Democratic opponent on the grounds of personality or fitness to be President.

Some people may think it's out of bounds but I think there are some very important reasons to challenge Hillary's fitness to be president. She's fundamentally dishonest and acts above the law. She has no accomplishments of any kind. To the contrary she's had a disastrous tenure as Secretary of State and acts secretively, in denial, and is wooden in most encounters requiring spontaneity.

Can you imagine any candidate challenging Hillary's fundamental honesty? (and please don't mention Carly Fiorina, who gets tripped up and defensive about a simple question about global warming). Can you imagine any Republican, except Trump, creating ads entitled "Hillary the liar" or "Watch Hillary go looking for the truth" or "Hillary investigating self, details to come soon"?

That's why I think if Trump is the nominee, and he acts towards Hillary the way he is acting towards Bush, he'll beat her hands down. Democrats are simply unused to Republicans fighting back at all, much less the way Trump does.

I still have no idea (even on immigration, when he talks about letting the "good ones" back in) what Trump will do as President, but if he's nominated, I think he has an excellent chance of winning.
