Excerpt: From PoliticalMoneyLine.com, here's a list of those corporations [PAC'S] that exclusively, or nearly so(90-100%), support only the Republican Party over the Democratic Party in financial contributions. (I've highlighted the "obvious" companies to avoid.)
Phillips Int'l. (100%)
Cooper Industries (100%)
Flowers Industries (100%)
Harris Corp. (98%)
Illinois Toolworks (97%)
Outback Steakhouse (96%)
ExxonMobil (96%)
National City Corp. (95%)
Wendy's Int' l. (93%)
Anadarko Petroleum (92%)
Timken Corp. (91%)
Halliburton (91%)
Meadwestvaco Corp (90%)
Darden Restaurants Inc. (90%)
Branch Banking & Trust Co (90%)
Int'l Paper (90%)
Here's a few more in the 80-90% range:
J.C.PENNEY CORP. INC. 89%
GOODYEAR TIRE 89%
CONOCOPHILLIPS SPIRIT 89%
SMITHFIELD FOODS INC 88%

CIGNA CORPORATION 83%
OWENS CORNING 83%

Excerpt: "Overall, the list of Corporations that give more than 50% of their contributions to the Republican Party numbers 254. On the Democratic side? There is only one Corporation that gives above 60% to the Democratic Party, CableVisions Systems at 78%, and 22 others in the 50-59% range. It's a 10:1 ratio in the number of corporations favoring Republicans over Democrats, but for the actual money, it's much higher, 25:1 or greater."
