I dunno cback, there are plenty of right of center(re) donors who put their money where their wallet is. The left wingers are happy to skew elections to destabilize, the right does it to get monstrous, no bid pork contracts? No doubt, there's a steady component to left wing "activism", but recent years has shown your exponential growth.
I think, the only, true as can be, "activism", or organic movement that arose from nowhere, was the President Trump election. jo didn't have activists pounding the ground. He had big money, how else would he have compliantly signed the order, killing the Keystone on day one, when he slept through the campaign, tucked away in care home conditions. No, watch any left wing activism? There are always well paid choreographers, dressing the actors in matching t-shirts, "organically" having professionally printed signage and luxo buses, spontaneously contracted to wisk in pros?
Having a relative younger child, you should be well aware that their schooling and stimulus, make it far more likely for them to nod in agreement with tru-jo and their ilk, than you would have gotten out of your early schooling. One big money has useful dupes, the other is a rino hedge fund, good ole boy's club.
