I will note that everyone here was saying this about Ossoff and Warnock two years ago.
True, but at least they did have
some useful political experience. Ossoff ran for Congress in the GA-06 special in 2017, and he clearly learned from the experience; his 2020 campaign was far better. Warnock was a political activist for years before running for office. Similarly, Mark Kelly is married to former Rep. Gabby Giffords and was active in the gun control PAC they started after her shooting.
Walker, Vance, and Masters have zero political experience that I know of, while Oz has a minimal amount (he was on the President's Council on Sports, Fitness, and Nutrition).
