I mean, it is basically the same dynamic. Right?

People vote based on a prediction of what they think will be a "good" outcome for themselves, the ones they care about, and probably society as whole (for some folks anyway), and they [spend money] to do so. Erm..or that's the theory...let's ignore all the misinfo, short-term emotive-not-substantial-issue optimization, special interests...etc

Basically, your "single example" is the governing system of most of the 'Western liberal' world.

What do you think about that?

[spend money]: People are spending real money to vote (not just in supporting donating to a candidate) but by how they expect their choices will cost them or reward them financially (and of course there are other 'non fiscal' costs and benefits associated to different choices). I guess you could argue that's different but to me it seems it's pretty much the same.
