Here is how the 2008 Democratic and Republican Parties presidential tickets will shape up, according to Ed Koch, who appeared on NY1 last night with Al D’Amato and Carl McCall:

Hillary Clinton, with Barack Obama as her running mate, against John McCain and Rudy Giuliani.

As for why Giuliani would take a backseat to McCain on a national ticket, Koch explained it’s because “he’s young enough to dream” that he could still be president.

D’Amato warned his party not to underestimate such a Democratic ticket — Hillary’s fund-raising, Obama’s charm, etc.

But McCall, it should be noted, poured cold water on the idea, saying who that Clinton would need a Southern Democrat in 2008 — John Edwards? Wes Clark? Bill? — because she and Obama represent similar portions of the Democratic Party.
