More evidence directly on this issue:
Republicans are the party of the rich, right? It's a label that has stuck for decades, and you're hearing it again as Democrats complain about GOP opposition to raising the minimum wage and extending unemployment benefits.
But in Congress, the wealthiest among us are more likely to be represented by a Democrat than a Republican. Of the 10 richest House districts, only two have Republican congressmen. Democrats claim the top six, sprinkled along the East and West coasts. Most are in overwhelmingly Democratic states like New York and California.
It's a free country, of course. And if the wealthiest want to support Democrats, that's their right.
If this is news to you, there is a reason you haven't heard that the Demcorats are the party of evil rich people.
