Yes. It's based on the principle of one person, one vote. Why should anyone be allowed to use money, just because they have it, as a means to have greater influence? If you look at the stats, all the parties rely for a significant percentage of their funding annually and during an election, 40% of it, usually from a small pool of about 5% of donors. That's fundamentally undemocratic. Loans should be limited as well. To be able to go to a financial institution that is federally regulated and get a huge loan to pay for your election, and then win power based on that loan, they've done you a huge favour. That causes a conflict of interest.
