Yes, Donald Trump will probably try to dismantle some of the rights that we currently have by appointing anti-abortion judges to sit on the high court. If Americans want to keep the rights that they are used to, they need to make sure that Donald Trump does not get in office.
Hypocrite that he is, I'd love to know how many abortions Trump has arranged for his various mistresses over the decades. When it comes to the actual topic of abortion, I can't imagine Trump losing a moment's sleep over the sanctity-of-life question. He is the ultimate self-righteous hypocrite! Despite what Trump believes, he has no authority to revoke established law.
Trump said that he is now anti-abortion. He doesn't mean it. He also said that he now believes Obama was born in the United States. He doesn't mean it. Trump will say what he thinks will get him elected. Once he is elected, he will do whatever he wants to do.
No, Trump will not appoint anti-abortion judges to the courts because he will not be president. If he were to get elected, he would, but his decisions would be vetoed. Thankfully, the American people will not choose to elect him and he will go back to being a celebrity who spouts hate.
