Scott Walker is white trash
Never underestimate your adversaries.
Here's where I think you guys on the "further left than I am but never mind" get it wrong.
If the fundamental conflict in America today is between the haves and the have nots, between the rich and working people, then running Walker (a guy of middle class background from the midwest) against Hillary (gets paid six figure speaking fees from Wall Street One-Percenters) is a stroke of genius.
If you assume that 45% on either side will vote for the person their party puts up, but the 10% in the middle will vote for the person they feel more comfortable with, Walker is VERY formidable.
And trying to use "elitist" labels like "White Trash" or trying to trip him up on Evolution (which most Americans don't understand or believe in) isn't going to work for you.
