How come?

So lemme get this straight.

We’ve got a dem house, senate and president. They are the majority. And for the last two years they have failed to give the people of the country what they want/need.

But if we don’t vote to keep them in power, then another group will take over and not give us what we want/need on a much grander scale.

And no one has even noticed the most obvious problem with that logic. If the only way to govern according to the will of the people in this country is through one-party rule, then how are we still a democracy?
