From a legal standpoint, having states attempt to individually decide on eligibility for federal office under the US Constitution was bound to end up before the US Supreme Court. That's not a surprise.
Probably the best outcome we can hope for is that SCOTUS will say that a conviction for insurrection would be needed to make Trump ineligible.
But we should not rely on the courts to save us from doom. We need to start right now talking up democracy, getting every moderate to liberal eligible voter to register and vote, and be more visible about supporting Team Blue. Preaching to the choir may feel good but we need to go forth and do some political missionary work.
Relevant to the cartoon: Actively remind people that it's the president who nominates US Supreme Court justices and it's US senators who vote to confirm them. Useless "protest votes" for impotent third parties can have a catastrophic effect on the federal judiciary for decades.
