Voting is usually about voting for the candidate you dislike the least. You should assume that both candidates are of doubtful character or worse.
If you have a choice, never vote for a lawyer. I've worked with lawyers my entire professional career. With a few exceptions, they are without any sort of moral compass. It is not their nature (or legal training) to possess such qualities. By profession, lawyers are solely motivated by money or personal gain; and they will readily join, support, lie for and defend any person (serial killer, fraudster, corrupt business owner, etc, etc.) if, that is, the money or their personal promotion is sufficient. Politicians who are lawyers are not the exception. They are the 'rule.' I once read that politicians have a lower public approval rating than 'used car salesmen.' Actually, I think that is kind of unfair – comparing a hardworking used car salesman, just trying to make a living, to a politician selling access and favors to the highest bidder.
Nonetheless, I encourage you to vote if you know a modicum of history; and have read the U.S. Constitution – particularly the Bill of Rights. I might also recommend the Declaration of Independence and the Gettysburg Address (which I was required to memorize in high school).
Don't be swayed by campaign rhetoric. It's mostly lies anyway.
While I'm at it, a few other requests from Grumpy: Make me proud. Study in school, work hard in life, live healthy lives, and conduct yourselves by the Golden Rule – 'treat others like you would want to be treated.' Have I always lived by those tenets? No... I'm sorry to say that I do have regrets; but you have a fresh opportunity to be better than me.
Oh, and always stand proudly with your hand over your heart when our flag is displayed and the national anthem played. Countless men and women have died to preserve that flag. Always remember their sacrifice. What's that got to do with voting? Well, if you are willing to stand for the flag, I will have faith in your good judgment when it comes to voting.
