Why do all these exceedingly well-off [Democrats] keep trying to convince us we’ll see them at the dollar store?

It’s all part of the increasingly delusional myth Democrats tell themselves that they are the tribunes of the middle class. In fact, their party is a strange two-headed beast -- picture a Cerberus featuring the faces of Barbra Streisand and Lois Lerner.

The Dems are a coalition of ultra-rich cultural-elite donors on the one hand and government employees and their clients on the other.
