That's their budget on paper. Donors don't have to disclose all their donations:

... nonprofits like Crossroads GPS and trade associations like the U.S. Chamber of Commerce are allowed to keep their donors secret. As a result, there is a great flood of campaign spending this election cycle for which there is no official paper trail.

I don't think the proper response of rich Valley people is to ramp up their donations to PACs unless it's the Wolf-PAC which is organizing to pass a Constitutional amendment to reform campaign finance and lobbying:
