It's not just the impulsiveness, he is extremely self-involved and disrespectful of others as well as the rules and courtesies which drive civilized life. He is ready to turn everybody and everything upside down to satisfy his own whims. Has he stopped for just a second to consider what the consequences of a last-minue cancellation of a televised national presidential debate that's been set up for months actually are? What this would do to Mississippi? The issues of TV time and ad time, all booked months ago? Does he understand how unfair he is being to the debate organizers, holding their debate hostage until the very last minute? What about the state of Mississippi, which has been gearing up to this event, proud and excited? How much money would be lost? How many lawsuits? This isn't a high school project, it's the presidency of the United States and the national stage.

Such unreliability, disrespect and chaos would be ill-suited to the most high-ranking office in the land.
