We shouldn’t be surprised that Tarkin is a sleazy, Republican apologist for the Emperor but not a diehard fanatic a la Boebert, Greene or Gaetz; he’s carved from the more cynical branch like McCarthy or McConnell. Sure the Death Star killed a couple billion people, destroyed a planet vital to the economy of the Core Worlds and cost enough money to bankrupt the galaxy. Those very valid points are insignificant because the Emperor needs absolute authority to defeat the Rebel Scum who are threatening the Empire’s security and prosperity…never mind he caused the Republic’s collapse 32 years earlier.
Meanwhile, ex-Chancellor Valorum’s defenders continue playing the What If…game and blaming the more Leftist Senator Sa’anders of Bakura for campaigning in the same infamous election caused by the Naboo Crisis. They often decry, “If he didn’t run, taking away votes from the Inner Rim, the Republic would still be around and we’d be enjoying brunch on Coruscant!”
