A headache . . .

. . . is what I got after reading this convoluted article by Professor Akhil Reed Amar on how Sen. Hillary Rodham Clinton, (D-NY), and Sen. Barack Obama, (D-IL), could serve a co-presidents, or something like that.

But which should it be: Clinton-Obama or Obama-Clinton? In fact, voters in November could actually endorse both versions of the ticket—truly, two presidents for the price of one. How? The Constitution’s 25th Amendment allows for a new paradigm of political teamwork: The two Democratic candidates could publicly agree to take turns in the top slot.

Then, at some agreed upon point, the President would cede power to the vice-president and, with Congressional approval, become the vice-president. The same team would then run for re-election four years later and four years after that, after which one of them would have to drop out because they would have been elected president twice. The remaining person could then run for president on his her own power.

Akhil Reed Amar teaches constitutional law at Yale University and he wrote “America’s Constitution: A Biography.” He is also a winner of the American Bar Association’s 2006 Silver Gavel Award. He is, in other words, a very smart guy and he said this could be done.

Whether it should done is, of course, another matter entirely.
