Reasons: Spread the Wealth, Joe the Plumber, his arrogance, and kicking conservative newpapers out of his campaign.
I work in management for a union shop constuction company. A handful of solidly-tradition labor Dems that work here say they just can’t vote for 0bama.
My sister-in-law, another “solid” dem, is going for McCain. Apparently she’s fed up with all the crud she has to fill out in the HR deparment she works for. Sick of regulation I’d guess. Her husband—my brother—is a co-owner of an electrical business. He always let the better half rule the roost when it came time for political opinion, and he may be doing that now, but I don’t think so. He’s just now “getting it” with all the barriers he and his partners face trying to make the company grow and go. In spite of his mate swaying him in the past, he’s seen the light and is coming over from the dark side this time around. I reckon my regular pontifications at the Sunday gathering at Mom’s may have done the trick.
