More evidence has surfaced that Donald Trump's Iowa ground game is not very substantial.

One volunteer leader enlisted by Donald J. Trump to turn out Iowa voters has yet to knock on a single door or to make a phone call. Another is a "9/11 truther" with a website claiming that the Sept. 11 attacks were a government conspiracy. A third caucus precinct captain ... said the campaign's goal of having them each enlist 25 supporters was unrealistic.

"There's probably not even 25 registered voters in a precinct," said the captain, Kathy Hawk. ...

 "I got 12 to go to the caucus, but I don't know if they will actually vote for Donald Trump," said Rick Shaddock, a precinct captain in Fairfield and the one who maintains the Sept. 11 conspiracy site.

Remember, caucuses require a lot more pushing and handholding to get people to come out than primaries.  That's why I suspect that if Ted Cruz is a little bit ahead in the polls, as he is in the latest Des Moines Register poll that came out Wednesday, it will only understate his advantage.  Donald Trump hasn't set up a substantial ground game in Iowa, and what ground game he has is run by inexperienced and/or nutty people like the 9/11 conspiracy theorist.

I have to wonder: how is Donald Trump going to manage our government effectively when he can't even seem to manage the relatively simpler mechanics of a campaign ground game?  If he thinks all he needs to do is to give speeches to get people to come out and caucus, he betrays a fundamental lack of understanding how the system, and human nature, really works.
