I vote "other" / third party when I have a good feeling that the Democrat / Leftist will lose the election anyway. I vote Republican when I think my vote is necessary to help stop a Leftist Democrat from gaining power.
Here in Arizona, I actually like Krysten Sinema as a Senator. I have reservations about voting for her because she's a Democrat and that will put or keep the Democrat party in power. When she was younger and running for state offices she was very much a Leftist and there was no way I'd vote for her. But she's grown up and is now much more of a centrist only in a party that could care less what the Center thinks or wants.
With many, many politicians, their choice of party is only a choice that they believe will put them into office. I may not like diesel engine exhaust, but if the bus takes me where I'm going, I'll ride it.
In our current Uni-Party situation,
EVEN IF a conservative is elected as a Democrat, they are obliged to support that party's leadership. A conservative Democrat in Congress will STILL vote to appoint Pelosi or Schumer as their leader.
The REAL goal of our Uni-Party is to assure that there can NEVER be an effective Third Party. That is why so many in Washington on both "sides" opposed Trump so passionately. He was constructing an effective Third Party.
If you are an American who strives to earn a living, has a family, wants the best for your kids and hopes to simply live in a safe and secure country, you are opposed by the oligarchs of the Uni-Party.
The ONLY person working to advance the interests of the average guy in national politics that I have ever seen in my unexpectedly long life is Trump.
BOTH of the major political parties labor tirelessly to steal to maintain the oligarch classes and the systems that enrich them and diminish the little guy even more.
While elected politicians pander to the little people to get votes and to get useful idiots to help steal elections, they hate us. They detest the indignity when they are forced to be near us and resent those times when they are forced to communicate with us.
The now openly abusive oligarchs running the Social Media Platforms arrogantly and impudently cancel, censor and shun political opponents.
We live in interesting times. So did the folks working in the cotton fields in the Antebellum South.
