Yes, there were demonstrations calling for him to run. And surely they were genuine: I mean, there's no way a guy who spent all those years running the intelligence service could bring people out into the street in his name, is there? No built-in constituency of old Mubarak spooks? Nah. I'm sure it's grass-roots.
And I'm equally sure no one has already been quietly collecting all those signatures he's going to need to have in place by Sunday.
UPDATE: From Ursula Lindsey at The Arabist's reaction to the Suleiman candidacy, I get the sense she's not enthusiastic:
But creepy Mubarak spy-master Omar Suleiman has also apparently just announced he will join the race! . . . Suleiman as Egypt's next president would really be ten times worse than a slap in the face to the revolution (it'd be more like a foot endlessly stomping on the face of the revolution...) That said, I'm surprised by news stories calling him a "front-runner." in a recent Al Ahram poll, he had 10% of the vote. While he can count on the police and intelligence communities, reactionaries and morons in search of "an iron fist," I think a majority of the country would never vote for him. They'd have to rig it to get him in.Oh, go on, tell us what you really think.
