I don't see that. What I have learned from past experience is that the big money boys would rather have a liberal in charge than a conservative. I would bet they would back a third party candidacy or even Obama himself before they would ever think about supporting a "loose cannon" like Bachmann.
Personally I doubt we will ever see Bachmann nominated especially once Perry enters the race. He will take enough voters away from her to keep her from winning. He will be billed as the conservative who can beat Obama and many Republican voters will fall for it, not to mention all the Dem crossover voters messing with the primaries. Heads they win, Tails we lose.
The banks, insurance companies, and the union goons may still love Obama, but the US Chamber of Commerce, Club for Growth, and medical professional associations hate him with a purple passion. Whoever wins the Republican nomination will get backing from the people Obama has PO’d, and they’ll spend millions more running negative ads against him during campaign season.
Although I agree with you that if Perry sticks his thumb in the gravy bowl, he’ll ruin it for conservatives, and Mitt’s about 95% sure to win the nomination. Really no point in sending money to other presidential candidates until RINO Ricky makes up his mind either way.
