Trump has hit a very interesting cord and it is resonating in a HUUUGE way. You don't hear the shop worn mantra of the establishment republicans --limited government , regulations , get government off your back and the private sector will solve the economic inertia and grave loss of upward mobility that has beset the country.
Trump offers a nationalistic message stressing economic populism. The government is not by definition bad , he insists its the politicians that sell the public down the river in exchange for cash and lobbying gratis. He insists "he can make the government win and that stupidity, incompetence and self serving greed is what has undermined America, NOT the government itself.
He is essentially a pro-government republican , that promises smart thinking unencumbered by political bribes and their follow on control, can change America in a positive way.
He has so much in common with Sanders its amusing---- the government is bought and paid for by corporate power that emasculates its ability to respond to the country's needs----sanders and trump agree----trade and trade deals since Nafta and through TPP have been pushed by both parties and have been a disaster for American towns and American manufacturing---sanders and trump agree----that foreign wars especially Iraq and Lybia were gigantic blunders , destabilizing the entire region , giving rise to Isis , & underpinning the mass migrations threatening to destabilize the order in europe....again Sanders and Trump agree.
Trade, the overwhelming influence of the oligarchy and their parochial interests , and the foolish and misguided adventurism in the middle east have brought us very little that's good.
As Trump says " they are all puppets , they do whatever they are told , I know these people and many of then are not nice people and none of them have the interest of the country topping their agenda."
Trump has his flaws no doubt , but all three of these critical issues that underpin both his and Bernie's message, are essentially TRUE and more significantly most of the electorate agrees that they are true even if they disagree on solutions.
Trump had ZERO shot against an array of contenders that were a who's who of republican politics----Bush the heir to the dynasty , walker the Koch brothers pet and the one everyone feared---Rubio the sharp young up and comer, Kasich the steady hand that delivers ohio, Cruz the religious zealot , Christie the guy everyone wanted last cycle etc etc etc....
Trump has buried them all with a powerful message that transcends the PUNDITOCRACY that daily ridicules the lack of substance. Now its likely Kasich will get out in two days , and Cruz after digesting the 35 point explosion for Trump in California soon after that.
Trump may be an eccentric character , rude, vulgar , a bit of an egomaniac, a guy that lives in a golden penthouse and has a mild germ phobia.
But he has won the nomination against all odds , he will compete in blue states like Pennsylvania , Michigan and several others....he will win every state Romney did and the entire election will be fought in swing states and blue states.
After what Trump has done to the premiere varsity team of republican governors and senators---underestimate him at your own risk!
