The Federal Election Commission has created a Campaign Finance Disclosure Portal which provides detailed financial information on how much money has been raised by the presidential candidates and candidates for the House and Senate in all 50 states. The database includes the names of individual donors and political action committees and how much money they have given. Most of the money contributed to Vermont candidates for the U. S. House and Senate seats comes from out of state and the list of PAC contributions is both fascinating and surprising.
The Vermont Campaign Finance Disclosure Reports website provides data on contributions to the campaigns of Vermont House and Senate candidates and other elected state officials.
