Attack? Heck, until only a very few years ago, he donated more of his hard-earned money to "the DEMS!!!" than to Republicans, of $1.3 million, for every $47 dollars than went to the political campaigns of Republicans, $53 went to Democrats!
Oh, sure, as a businessman, it was only the cost of doing business, which is always pursuit of financial gain; it was only what he had to do to increase profits to his shareholders and himself.
In business, being apolitical -- without reference to politics -- is good for the shareholders, if often bad for the cause of liberty (helping to get Harry Reid elected, which Trump did as a "cost of doing business," harmed the cause of liberty, let's face it).
Businessmen should stay in business, where the goal is always to grow and prosper. Only a politician with a limited government political compass, one that has been consistent over the decades (look at Ted Cruz) has the mindset and the skills to do the opposite with government than what a businessman does with business. Government and politics should be worlds apart; politicians should represent us in matters of government, and businessmen should concern themselves with profiting themselves and their shareholders.
Leave politics to men guided by political compasses, and business to men who put politics aside to benefit financially. Had Trump not done that ... we'd never have heard of him. Had the Founders done what Trump did ... we'd never have heard of the USA. They not only put politics above financial gain, they put their properties, businesses and lives on the line for political principal, no "cost of doing business" to support the Crown.
I respect Trump, I love the guy, and I believe he is a true blue well-meaning patriot. But he is an apolitical businessman and showman at heart. Ted Cruz is a politician guided by pretty much the same political compass I follow, and which guided the Founders.
Cruz all the way to victory and liberty.
Put Trump back to doing what he does best -- increasing shares for his stockholders.
