Conspiracy to evade federal election laws

So my donors have maxed out what the law permits them contribute to me, and your donors have maxed out what the law permits them to contribute to you. Why don't my donors contribute to you and your donors contribute to me?

The AP reports:

Barack Obama told Hillary Rodham Clinton's top financial backers Thursday that he personally has donated $2,300 to her campaign and more significantly has asked his biggest donors to help pay off her more than $20 million debt.

Obama made the announcement at a meeting with Clinton donors who have been frustrated that the Democratic presidential nominee-in-waiting had not done more to help her pay the bills even as they are expected to help fund his campaign.

The size of Obama's donation is the most he can contribute under federal law.
