JIM GERAGHTY: Tim Walz Loses His Bubble Wrap.

On the menu today: J. D. Vance fans, last night your man won his own personal Super Bowl. Tim Walz fans, your guy may not be ready for the major leagues. The good news for the Minnesota governor is that there’s not a single smudge on any of his timepieces, and he can clearly see what time it is . . . because Vance absolutely cleaned his clock.

Walz Seemed Small on the Big Stage, and He Knew It

Being a Democratic statewide official in a deep-blue state ranks among the easiest jobs in America. Once you’ve won your primary — which can be hard fought and nasty — you’ve got that job until you choose to retire, or until you are term-limited out. It’s extremely unlikely you’ll lose a subsequent primary, because while neither party tosses out incumbents much, Democrats almost never do it. (That’s usually the case down ticket as well; of the 2,214 Democratic state legislators who ran for reelection this year, 98.5 percent won their primaries.)

What’s more, your state’s media will often be a wind at your back. Your gaffes will rarely matter; scandals, mistakes, and policy failures will be explained away; you’ll always have the fundraising advantage unless you’re challenged by a self-funding billionaire; and no matter how bad you are, the biggest names in your state’s media world will always endorse you for reelection. What are they going to do, vote for a Republican?

Democratic statewide officials in deep-blue states lose their jobs so rarely, they might as well have tenure. They play the game of politics on easy mode.

That CNN report that Walz was nervous might not have been expectation-setting spin after all.

The Minnesota governor looked like a guy who had no expectation of being on a nationally televised debate stage three months ago, and who realized early in the night that the moment was too big for him. His default facial expression is one of worry; he does not have a commanding presence. He looked down to take notes so often, someone on social media asked if he was working on a crossword puzzle.

Perhaps if most journalists weren’t Democratic Party operatives with bylines, they would have fewer not ready for primetime politicians. But then again, don’t discount the person who advances them to the big leagues:
