Once there was a loud, brash, egotistical celebrity who decided that he would run for the highest office in the land. He said outrageous things, attacked the current political system and didn't care what anyone thought of him. He rallied the people who were sick of the business-as-usual, "my friend across the aisle", bland, polite politics.
For their part, most political pundits wrote him off as a joke, declaring that he couldn't possibly win. He was attacked from both the Left and the Right. His supporters were constantly disparaged as moronic rubes who weren't sophisticated enough to understand the mystical inner workings of politics.
His name was Jesse Ventura...and he won.
His administration as Governor of Minnesota was a disaster. He was constantly attacked by both Republicans and Democrats and he took every attack very personally, thus making policy to hurt his opponents rather than for any good it would do for the state. It was a three-way war that lasted for six years.
I suspect that Donald Trump's administration would be similar.
I'm not bashing Trump here. He's not my guy, but it's fun watching him poke the Democrat and Republican elitists through the bars of their cages with a sharp stick. If only one of the other Republican candidates would get the hint: "That is what we are looking for! Do that! You don't even have to be a complete asshole about it like Trump is! Just quit pulling punches and speak the damned truth instead of worrying about who you're going to offend! The people who are offended would never vote for you anyway!"
So far, the only person that I see who would be capable of this would be Ted Cruz. He is my guy, and I'd vote for him in a heartbeat. Faster, if he completely took the gloves off against the elitists in both parties.
I witnessed what happens when you elect a thin-skinned, emotionally childish person to the Executive office. It ain't pretty. Trump isn't the answer, but I admire him for doing what he's doing.
