Should we be surprised? Salon says that American Crossroads, Karl Rove’s new self-described “grassroots” organization, has actually received 97 percent of its $4.7 million from just four billionaires. Three of those men come from Texas, and two made their money in oil and gas. Rove better shake these men down some more though, if he wants to meet his stated goals: American Crossroads has pledged to raise $52 million to beat the Democrats in November.
