ActBlue website donor information contradicts an Avalon spouter'

Avalon - ActBlue website donor information contradicts an Avalon spouter's claim that ActBlue is nothing more than a front for wealthy donors such as George Soros. For example: 60,816 donors contributed $1,160,827 to the Support President Obama's Agenda campaign. 38,504 donors contributed $1,013,600 to the Help Elizabeth Warren Win campaign. 33,540 donors contributed $1,165,406 to the Orange to Blue 2012 campaign. For those three campaigns the average contribution is $25. Other campaign averages among the "Top Contribution Forms" range from $19 to $33. How much is the average Koch brothers' donation?
