Maybe he's getting so much money from the types of corporations he is against because they hope he'll reverse himself on his policies.

That sounds ludicrous, but there are many reasons someone would donate to a campaign that don't just revolve arouond helping to elect someone. And, as a candidate, are you really going to argue with someone who's offering your campaign buttloads of cash?

Personally, even if it was money coming from the most despicable industries in the world, I wouldn't say no.

Unless they told me to do something for them in exchange for the cash.
