Is it all or nothing? Flip a switch? Or are we doing the things that will either insure a bright future or a dismal one?
Look at the letting in of 8 million+ illegals so far. Why? Have already heard liberals talk of amnesty and putting them on the road to citizenship. Why? Who benefits from doing that? If there aren't enough.jobs for them will they become dependent on the Democratic Party since the Republican Party thinks they should be removed? And if they're dependent and newly minted citizens who do you think they're going to vote for? Why would the Democrats do all of this? Because it gives them a permanent edge in voting. We've already seen recently the direction the far Left is taking the Democrats. We've seen the direction that major liberal states have taken with economics, crime, homelessness, and drugs.
You seem to want immediate proof that the Democrats are ruining the country. They're well on their way in parts of the country and with complete control we'll have a permanent dependent class supported by everyone else in higher taxes. Socialists have learned that winning revolutions with guns leads to failure. It's indoctrination of children, and winning at the ballot box that brings them success in the long term. Success for them, then failure for everyone else eventually. But they don't care as long as everything is equitable except of course for them as the ruling class. Meet the new boss, same as the old boss.
