Who stands for stability?

WHEN Cuauhtemoc Cardenas first said he intended to become mayor of Mexico city at the start of the year, it looked like a last desperate grab for glory. The son of Mexico's most revered president, he had twice led the country's left in failed campaigns to dislodge the Institutional Revolutionary Party (PRI) from the presidency. But now, a month before the July 6th vote for the mayor's post, he looks almost invincible. A victory for Mr Cardenas would propel the leftist Party of the Democratic Revolution (PRD) back to national prominence.
