If you ask most people about me, they'll tell you that I'm a democrat, or a liberal, depending on who you ask. And yes, I most definitely side with the democrats on many issues. However, that does not make me any less concerned with who the Republican Party has decided to make their nominee. This election, we decided as a country that we wanted Hillary Clinton (D) and Donald Trump (R). But you knew that. Lets cut the chase.
Proponents of both say Hillary will be the first women president, she has experience in a government role and has been successful at making policy; Donald has made strides as a business man, isn't from Washington and tells it how he sees it.
Let's focus on those three things about Trump. Yes, he's a business man, and has made himself very wealthy (though how wealthy is under stipulation, as he will not release his taxes.) But, he has started and failed quite a few business ventures, and to get started he was not only from a wealthy family and had the ties that come with that, he also received a $1 million loan from his father to start his business. That's a significant leg up, and I would be interested to see if Trump would have been able to make it on his own.
Next, we have the supposed good news that he is from outside Washington. While it would be good to have someone influence policy from outside the pearly gates of D.C., having someone with not even experience as a town selectman running the country does not seem like the brightest idea to me. He has no idea how to be a politician, no clue how to interact with other officials and make policy. It is the equivalent of saying "Well, this guy has won four Superbowls coaching football, he will certainly be the most qualified guy to run the U.S. Olympic Decathlon team. No, that makes no sense. Just because he is a "good" business man, does not mean he will have the first clue when it comes to running a freaking country.
Finally, we come to his knack for blurting out whatever comes to his mind. There's a fact I find interesting about Trump and his campaign, and that is that there have been times when people that work on Trumps behalf, won't find out what he has tweeted until the morning after, because he has to clear it with no one. He can get on his phone at 0200 and decide he wants to Tweet someone. Some say that's good, that he speaks his mind. I say that it leaves the door open for Donald to make some pretty rash decisions and say some things that should not have been put in the public eye. Which has happened. Also, having somebody with no filter as our president is not a good thing. Not in the slightest. A presidential candidate needs to be able to be tactful and respectful of other peoples beliefs, policies and the way they run their country. Imagine if Trump meets Putin, and decides to just rattle off all the reason why he thinks Russia sucks, or why Putin is a pansy. Not good for the presidency or our country.
So I challenge you to look at the things you call pros and see them for what they really are. A business man who has no issue offending anyone and not one iota of experience in politics, that some consider to be the best person for the presidency.
