A quick internet search shows that Trump has spent 38,000,000 of his own money. Oddly, he  characterizes this "self-funding" as a loan, but perhaps he plans to pay himself back at some point.  

Regardless, if you're lamenting the ridiculous sums of money spent on elections, we're in agreement.  If  you're saying that rich people should have more influence than non-rich people, we're not.

Not having financial limits is like saying that all people have free speech, but some people have more of it.
