Confusing reports for biggest fund raising day

I don’t get it.

I read something the other day that said that Hillier Clinton raised the most money in a single day at $6.2 million.

This article (as well as others) says it was $5.7 million by John Kerry right after he gave his nomination speech at the Democratic National Convention in 2004.

And this article says it was Governor Mitt Romney who raised $6.5 million in January.

So who is really right? Someone should get their facts straight!
