A buzz of excitement swept through Cairo on Tuesday, a day before its first presidential election since an uprising overthrew Hosni Mubarak, ushering in a tumultuous military-led transition. “This is the first time I’ll be going to vote in any election, and it’s definitely a big deal. My family has been talking about it for weeks,” said Ibrahim Farrag Hassan, 64, who sells toys in a small market in central Cairo. Around 50 million eligible voters are being called to choose Mubarak’s successor on Wednesday and Thursday with a run-off scheduled for next month should there be no outright winner. “This election will change things, whoever is coming will be scared of the people and will have to listen to them,” said Hind Ahmed, 25, a shop assistant at a lingerie store. “All my friends and family are talking about the elections all the time. It’s the first time in their lives that any of them are voting in a presidential election because this time the result isn’t known in advance.” Campaigning for the landmark poll ended on Sunday night, with candidates banned from giving any media interviews or making public appearances for 48 hours before the election.
