I have written extensively about the role of micro-donors (donors giving under $200 in the aggregate to a campaign) and micro-donations (donations under $200) to presidential candidates, especially to the Obama 2008 campaign. Now comes this CBS News report (based upon data from the Center for Responsive Politics) that micro-donors are playing a key role for a number of Tea Party candidates for House and Senate.
Of course, there’s big money behind the Tea Party as well.
