Picture the response ad that’s coming. Opening line: “The Democratic Party would never nominate a candidate who owns multiple homes. Would they?” Cut to photos of mansion after mansion, each tagged with its property value and synced to the sound of cash registers: $4.9 million, $6.6 million, $9.1 million. Grand total: $29 million, more than twice what ol’ Moneybags McCain’s properties are worth. Nail it down with a graphic citing the 2004 net worth financial disclosure — somewhere between $198,794,683 and $839,038,000 — and wrap it up in a bow with a shot of Barry O and his buddy Waffles palling around on the trail. Closing kicker: “The Democratic Party: For Multimillionaire Nominees Before They Were Against Them.” The script writes itself, boys. Chop chop.
