This piece by David and Marina Ottaway in the Cairo Review is not about Mohamed ElBaradei per se, even if it is illustrated with a picture of him, but delivers this assessment of his failings:
Mohamed ElBaradei, who emerged at various time as the great hope of Egyptian secularists, stands out as an apt symbol of the old elite’s political failings. He refused to run for president on the ground that Egypt was insufficiently democratic, but did little to make it more democratic. Nor did he seem upset when his supporters tried unsuccessfully to convince the military to name him president, skipping elections. He launched the Destour Party but also did little to build it into a viable force. After the July 2013 military takeover, he readily accepted an appointment as El-Sisi’s vice president. But ElBaradei resigned six weeks later, after the military dispersed pro-Morsi demonstrators in Cairo at a high cost in lives—Human Rights Watch reports that at least 817 were killed—apparently appalled by the violence that had been predictable ever since his appointment. Whatever ElBaradei’s commitment to democracy in theory, he was never ready to lead secularists in the hard struggle to make it a reality and was all too ready to accept unelected high positions in government.
Worth reading in full, as a an argument that the dominant position of the Islamists and failure of leadership all-around doomed the Egyptian revolution, although I think it has a few blind spots – such as ascribing too much intent to what those who rose up against Mubarak in 2011 wanted.
