The Center for Responsive Politics reviews the corporate donors to the coonventions this summer, most of whom have major issues pending before Congress. Eight corporations (AT&T, AIG, Microsoft, HP, GM, Global Crossing, Lockheed Martin and American Water Works) are nonpartisan — funding both parties’ summer bashes in equal measure, although most of them have favored the Republicans in other campaign contributions this season. The cost of the Republican Convention is an estimated $50 million, up from $30 million four years ago. The Democrats, who also spent around $30 million in 1996, are laying out $35 million this time around. Taxpayers fund $13.3 million of each convention (why on earth should we be paying for this??), and for the remainder the parties depend on corporate largesse. You can click through from this site to access lists of all the donors giving $100,000 or more to either party.
