Uncharacteristically Quiet On The DE Homefront

But then again the previously-schmoozy Joe Biden hasn't made an appearance all day ...

WILMINGTON, DE -- The stakeout press have been placing regular food orders with local establishments. But when Stefanie Miller arrived from Dominos, no one here claimed the delivery. Could it be that the Bidens, who are believed to still be home, are ordering in?

Miller started walking down the driveway to Biden's house, but was stopped by the county police officer stationed beyond the gate. After determining that no one inside had placed the order, the officer placed a call to "Chris," whose name was on the tag.

"It's a prank?!" the officer asked incredulously.

He then walked out of range of reporters to get some information from the pizza villain. There was a credit number on file, but no telling if it was valid. Or why anyone would target the Delaware senator at this time.

The Biden home has fielded occasional visitors today, including the senator's state director and daughter. We have not seen the senator or his wife, leading some to wonder if he may have snuck out overnight.
