MADISON (AP) - Three groups supporting Scott Walker's run for president have raised $32 million, which is less than what two of his Republican rivals have collected but on target with the Wisconsin governor's goal for this point in the campaign, his top adviser said Tuesday. The largest portion, $20 million, came from a super PAC. A tax-exempt group Walker created in advance of announcing his presidential run raised another $6.2 million, while his state campaign committee added an additional $5.9 million through June.
