Zero is a strong word, but I do believe the polls are illusory. The left will dump billions of dollars on the election while the republican standard bearer is tied up in the criminal justice system.
Yes, a wasted election is pivotal. Let's imagine a best case scenario after 8 years of Biden ... Thomas and Alito make it to 80, the democrats choose not to eliminate the filibuster and ram through every toxic menu item (starting with DC and Puerto Rico statehood, late term abortion everywhere, student loan forgiveness, eliminating tuition, universal preschool, inventing civil rights and protected classes, single payer health care, banning firearms, amnesty, expanding the supreme court, green new deal, federalizing election laws, atrocious foreign policy). Republicans manage to capture the senate and the white house in 2028. How will that administration get anything done? District and appellate courts will be stacked with progressives. Federal agencies will be radicalized as boomers retire.
