This is what I don't understand with American politics. When there is so much at stake why do they persist with this system whereby anybody with enough money can run? Why aren't the parties bringing through candidates, looking 5 or 10 years in advance, instead of grasping at mavericks or resigning themselves to incumbents? Perhaps they are and we just don't hear about it. The large sums involved in making a presidential run probably deter many decent candidates, making politics only viable for the rich.
Probably the same reason proportional representation doesn't look like it will get a foothold in the UK parliament for the foreseeable future. - Turkeys voting for Christmas.
I think Democrats spent years in disarray and somewhat ironically, it is probably Trump who has brought the Democrats (largely) together. Whilst Republicans had the likes of arch conservative Liz Cheney in their ranks as a potential leader, with Trump's malign influence over the party, her vote against Trump in his second impeachment trial and involvement as vice chair of the Jan 6 enquiry, effectively numbered her days in the Capitol.
Less wealthy people may be able to make it, but certainly with the Republicans, unless they can find someone charismatic who large numbers of people would be prepared to back, this would seem unlikely, at least for a while. Trump is bleeding the party dry. In 2023, his political action committees spent >$50m in legal fees for Trump and I would have thought he will be burning money through 2024 at a similar if not accelerated rate.There is an article
here which details some of the mind boggling figures.
Plus if, as seems likely, he secures control of the Republican National Committee that will give him access to more money.
Also in some states there is a cash shortage to support candidates. For example in the battle ground state of Michigan, the Republican party started 2023 with almost $2m cash on hand. It ended the year with around $246,000. In Arizona, another battle ground state Republicans are also a bit short of cash. In August/ September last year, the party disclosed cash on hand of
circa $15,000. By contrast Democrats disclosed >$3/4m.
