So what are these specific ways you believe he will destroy the country?
Please bookmark this post so I don't have to repeat and repeat and repeat this stuff every week. I don't have time to list all 99 reasons, so just a few will have to do.
1. Trump intends to weaken the First Amendment. He's blacklisted reporters from covering his campaign and he's stated he thinks the First Amendment should be changed to make it easier to sue journalists for libel.
2. He's turning a blind eye to Putin. He just said that Putin "is not in Ukraine". He said he might not honor NATO commitments to defend Europe. That's like a green light for Russian to invade the Baltic states. This could lead to escalating tensions with our allies and Russia. Possibly a new war.
3. Further, he's shown an admiration of strongmen authoritarians. He's praised Putin, Saddam Hussein, Kim Jong-Un, China's handling of Tiananmen Square. I expect he will adopt a similar demeanor as president. Imagine Trump issuing executive orders. He's said that "he will not allow companies to move their headquarters outside the U.S."
3. Trumpeteers go-to argument is that he will appoint good SCOTUS judges. How do we know that? He's walks back almost everything he says, plus he said his own sister would make a fine Supreme Court judge. She is a flaming pro-abortion liberal. We could get a couple of lousy appointees. You never know. (Don't bother with the "but...but...but...Hillary argument. Yes, she would be a disaster with Supreme Court appointees.)
4. Because he IS NOT A CONSERVATIVE
he favors big government solutions. He's says he's for a market based health insurance program and then in the next sentence he says he's "going to take care of people who are dying on the street because there will be a group of people that are not going to be able to think in terms of private or anything else.” Going even further, on 60 minutes he said, "Everybody got to be covered. I know that is an un-Republican thing for me to say, but we gotta cover everybody. Everybody's going to be taken care of much better than they are now. The government's gonna pay for it." The implication is a new federal health insurance system. He praises Planned Parenthood. He agrees with liberal SCOTUS rulings on eminent domain. He supports the ethanol mandate. He for raising the minimum wage, etc. etc.
5. Trade Policy. His proposed tariffs against China, Mexico, whomever, would raise prices for American consumers and fail to bring back jobs. For a supposed business genius (which he's not, witness his numerous business failings) he should know that a lot of 20th century manufacturing jobs, i.e. steelworkers, garment workers, many manufacturing jobs have disappeared because of automation, robotics, and increased production, not solely because of cheaper overseas labor.
6. The Mexican wall is a folly and will never be built. If it is built, it will never be completed. More likely, it will be a federal funding sinkhole for money, have cost overruns, and be plagued with corruption. Then the Mexicans will simply dig tunnels under the wall.
Don't have time to continue but I could...
