The largest 100 political contributions made during the week ending August 28 can be found in the table below, according to the Wisconsin Ethics Commission.
Donations made to political groups or candidates must be disclosed under state law for greater transparency in elections. While Congress created the Federal Election Commission to oversee federal elections in 1974, each state is left to regulate its local elections.
