Obama's Campaign Donations

When the news broke a few weeks ago that Obama had raised $150 million in a single month, I thought, that’s amazing, he must be really popular.  And maybe he is, but it turns out that a good portion of those donations are likely illegal, because Obama’s website is configured to not perform the basic address-verification that virtually all online payment systems require.  So illegal donations from outside the US, and multiple donations from the same person which exceed legal limits, are perfectly welcome in Obama’s system.
