I don't see how that reflects corporate influence on the Democratic party. Democrats stand for environmentalism and social equality.

How does a democrat, running on an anti-war platform, whind up continuing a war (Afghanistan) his predecessor started?
Why is it, 70% of the country is against these wars, yet we're still fighting them?
How does a President wanting to fix the cost of healthcare in America, whind up omitting the one thing (public option) that would've of drove costs down?
Why is it, that no matter whether a democrat or republican is President, whether republicans or democrats control the House or Senate, it's always business as usual in Washington?
Currently, there are 39,000 lobbiests in Washington collecting paychecks from various industry corporations. Now think about that. Company's do not shell out that kind of cash, without getting something in return.
