The Center for Responsive Politics (CRP) is a non-profit, nonpartisan research group based in Washington, D.C. that tracks the effects of money and lobbying on elections and public policy. I looked it up on all sides.com and apparently open secrets is unbiased and center political rating with 1,508 ratings. According to them, Trump has raised $642,206,315 overall this year and has spent $460,100,149. However Kamala Harris has raised a whopping total of $1,022,097,870 and has spent $707,146,612.
