Dennis Prager argues in a National Review Online column that conservatives should offer a clearer picture of their ideological foes.

Republicans — from the highest-ranking politicians to rank-and-file members of the party — fight Barack Obama, Nancy Pelosi, Harry Reid, and Hillary Clinton, and all other Democrats. But they don’t fight the Left and leftism.

The implication is that if only we could defeat this or that Democrat, we would be on our way to a much better America.

But it’s not true. If extraterrestrials came to our planet and absconded with every Democrat holding office from Barack Obama down to every Democratic city councilman in America, nothing would change. Other Democrats with the same left-wing views would take their place.

Leftism is ruining America. But almost no Republican ever — let alone repeatedly — says this.

The universities of this country have become a laughingstock. They have degenerated into anti-intellectual, anti-Western, anti-rational institutions with their ludicrous “safe spaces,” trigger warnings that infantilize students, and all the lies about the racism and a rape culture that allegedly pervade the campuses and American society.

What is responsible for that? Leftism.
