Yes, i think that political contributions to a candidate's campaign should be public information regardless of the amount given because the American public needs to be aware of how much influence that Wall Street and billionaires can wield over our elected officials. The President of the United States needs to put the interest of the American public above all else, hence they should be open with the American public about the people that donate to their campaigns.
I think that if people were more aware of what was being contributed for campaign funds, it would help them put into perspective the gain in popularity. It seems like money makes candidates more popular, and thus it would be only fair to disclose these numbers to the general public.
I think any money given to someone who is running for public office should be made public. The reason is that this is a public figure who may make important decisions in the future. I think it's important to know who gave large amounts of money to the campaign. Many people give to campaigns in hopes that they will be able to pressure the candidate once they're in office. It's good to know what types of people financially backed the candidate during the campaign.
Just like it is not considered appropriate for people to announce their salaries, it is not appropriate for a person's financial contributions to be made public, especially without their permission. A contribution to a political campaign is a personal choice, and a person should be able to make it without having to worry about what everyone else will think of it.
