I know people personally on both the right and the left that aren't millionaires but (nearly) all of the public and influential political actors I know are at least millionaires, regardless of affiliation.
You're counting your opponents as the second group and your allies as the first group. Someone on your opposing side could make the _exact_ argument by reversing the groups. It's telling that your statement does nothing to show what your actual politics are.
The people I support politically are generally wealthy. I am also fairly confident that the ones who aren't probably will be if they are in politics long enough and not necessarily through corrupt means. Anyone of that stature can, at the very least, sell quite a few books on their name alone for instance. It goes hand in hand that influential people can more easily amass wealth.
Sure, politicians can become wealthy after holding office. I'm more talking about where people were situated before they entered politics, and in particular the people who are not politicians - donors, influencers (for lack of a better term), etc.
And I think my politics are more accurately represented by normal people vs. career politicians than by donkey mascot vs. elephant mascot. I vote Democrat as a matter of lesser-of-two-evils, but I yearn desperately for a world in which no one who's involved in any way with DCCC can have influence in politics ever again. If you find me someone who votes Republican who says the like AOC and hate Trump, I'd probably agree with them on a lot of things.
Your politics are mostly irrelevant although it does help with examples...
What you said paints your political allies as people you know personally who are essentially "down on their luck" people who are trying to make it while your political opponents are millionaires the likes of Mitch McConnell or a Lindsay Graham.
Someone with the opposite political leanings as you could say that their political allies are the steel workers in Pittsburgh and the auto workers in Detroit who's job were lost to globalization and free trade (and they vote Republican as a lesser of two evils) while their political opponents are millionaires like Nancy Pelosi and Diane Feinstein.
You're using two different categories of people as allies and opponents.
If you cast your argument using the same categories, it doesn't make sense. Your allies, Pelosi and Feinstein are just as wealthy as your opponents, McConnell and Graham. Or inversely, your allies, the folks buying lotto tickets accepting below market salaries who just haven't joined the right startup are just as poor as your opponents, the factory workers and coal miners who've lost their jobs to globalization and technology.
I think you're trying to say your allies are both groups from the second example and your opponents are both groups from the first example but that doesn't really work because you're actively supporting half of each and actively working against the other half. You've chosen a side that you believe will help both sides, even though they are your opponents but I don't think that's a unique position to your side.
(And I think you'll find that I disproportionately support the non-millionare politicians.)
