It's not easy to discover, but I think Nancy Pelosi is worth a couple of hundred million, maybe more. She is never characterized as "wealthy."
In fact I seem to recall an article that disclosed that there were lots more millionaire Democrats in Congress than millionaire Republicans.
Of course nowadays, a million isn't what it once was. I assume pretty much everyone that appears in the media is worth at least a few mil.
A good point. She is definitely a centi-millionaire.
