Site the source of that quote. When and where did Trump say that. I am not denying that he said it I am just asking for verification. You need to understand that Trump was a hard core Democrat most of his life. If he said it prior to 7 or 8 years ago then he said it as a Democrat.
However, Trump has said a lot of bizarre and strange things. Like during his campaign when he said that he could shoot a man on 5th avenue in broad daylight and not lose a single supporter, I thought he was insane. The only thing that made it true is the fact that the extreme hatred coming from the left against Trump made his supporters even more devoted than I have ever seen to a president.
However, if he actually did say that, statistically speaking, he was dead wrong. Democrats have a real problem on their hands. Republicans, on average, have more children than Democrats. Democrats are literally breeding themselves out of existence. If it wasn't for the fact that Socialists have taken over our schools and colleges and there wasn't a 24/7 constant drumbeat of liberalism on TV and in movies the Democrat party would have died years ago. Your brainwashing efforts are working because there are fewer Republicans among the youth than before. But just as you have started to erode the Republican party, the Libertarian party is growing exponentially. Soon the Libertarians will over take the Democrats. Libertarians are also becoming popular with the youth. The Libertarian party is even more diametrically opposed to the Democrats because they are all about freedom for the individual and that all political power resides in the individual, not the government. That makes Democrats heads explode when they hear stuff like that because they are just aching to give all of their liberty over to the government so they can get "free stuff".
