In the last debate, I caught a glimpse on what I thought was a look of pity on Romney's part as he watched Obama speaking.
Maybe Romney knew what was coming up and that it would devastate Obama campaign, if not Obama himself.
Some have felt Romney held back some during the debate when he did not bust Obama's chops over Libya.
Maybe he knew these emails were about to be dropped by Trump, or someone else, as part of an October surprise and that Obama campaign would inplode without Romney having to do a thing.
If Romney had something truly killer on Obama, they wouldn’t want to lessen its cred by releasing it via Trump.
