I'd argue that we're more an oligarchy than a democracy. Yea we technically allow for a democracy but the reality is that someone with good ideas and no money is going to lose vs someone with bad ideas but a lot of money.

Especially with our first past the post voting system and the two parties ignoring the plebs whenever they decide on a candidate, ala the DNC pushing Hilary over Bernie. Trump getting picked when the Republican establishment didny want was probably the most democratic part of the previous election, but it wouldn't have happened if he was not independently wealthy
