The explicit goal of the republican party is they feel they don't need to get a majority of votes or voters in order to govern. He's making explicit what has been implicit for years now. They're an anti small d democratic party, so it is inevitable that they go back to the tried and true American tradition of voter suppression. They've inherited the anti democratic norms from immediately after the civil war and reconstruction through Jim Crow, still largely based on race, but now to "own the libs" generally.
