A blue collar traitor is a laborer who supports the G.O.P.
Eventhough Republicans are anti-labor and unions support Democrats, some blue collar workers actually vote Republican.Blue collar workers
work hard for their money and they are the backbone of a strong American economy. They actually make stuff (manufacture products, build buildings etc.) many of these laborers belong to unions, so they can help protect each other from greedy corporations.
These blue collar
people vote for Democrats because they are the party that supports the working class. The Republicans only look out for the richest 2% of the population and support the big corporations that finance their campaigns.
Congressman John Boehner (R-Ohio) is another kind of blue collar traitor. He grew up in a blue collar family and actually joined the Republican anti-labor party!
