Unfortuneatly, riply, it’s quite true, the Democrats are now the party of the “rich”.
The 30 wealthiest Congressional Districts in the US are represented by Dhimmicrats.*
I would add that there is more then likely 1 or 2 Republicans mixed in there, but on the whole, the Rich prefer the jackass to the Elephant...
However, here in New Jersey, the wealthy counties (Somerset, Hunterdon, Morris) vote most reliably GOP, while the urban and "blue collah" areas still vote Dem. In other words, we haven't changed in the Garbage State.
