In the United States, The Left is always childish, impractical, ignorant, silly, and unserious. Liberal solutions to liberal concerns have been taken off the table, replaced at best with conservative solutions to liberal concerns. Serious people know such compromises can get through Congress with a bunch of bipartisanyship, until, as always, Lucy pulls the football away. And even when conservative solutions are proposed (tax credits! insurance exchanges! incentives!), they're a Rube Goldberg mess that people have to fight for constantly.
In the richest country in the world (close enough), life shouldn't be so hard.
