Why does Rubio get Walkered on the left

[Bismarck]

With Walker they were peeved about losing in Wisconsin, a state where labor had long dominated. They underestimated him and he beat them. With Cruz the most common reason I hear people say they don't like him is his face, I think republicans hate him as much as dems do. The sudden vitriol against Rubio is just sensing weakness in our strongest candidate. They saw an opportunity with the bad debate and pounced.

Watching liberals have meltdowns over Walker and Cruz is the best thing about Walker and Cruz.
