RNC: Why didn't Edwards endorse sooner?

The Republican National Committee has its own take on John Edwards' endorsement.

RNC Chairman Robert "Mike" Duncan released a statement this afternoon: 

"Barack Obama and John Edwards share an out-of-touch agenda that would raise taxes on families while cutting funding for our troops. The only question is why didn't Edwards endorse sooner? Edwards' endorsement of a candidate he previously blasted as inexperienced, hypocritical, and lacking substance will not help Obama with voters looking for real change."
