Choose the Blue. A site which lets you know which American companies support which US political party, in order to let you buy only from those which support your political leanings? It’s quite a scary concept if you take it to its logical conclusion. Of course clever companies like Intel split their donations almost 50/50!
If each American who voted for John Kerry spends $100 in 2005 on a Blue company instead of a Red company, we can move $5 Billion away from Republican companies and add $5 Billion to the income of companies who donate to Democrats.
Since business is what makes America strong, from a global standpoint, it is much better to support the Red companies.
