Senator Carlos Navarrete declines - and backs Barrales

It was not a big surprise that PRD Senator Carlos Navarrete declined from the contest to be the left's mayoral candidate for Mexico City - despite heavy campaigning he simply was not rising in the polls - but what does surprise me is that Navarrete declined in favor of Alejandra Barrales. Given Navarrete's not inconsiderable political capital, that means that Miguel Mancera will face a stronger challenge to defeat Barrales for the nomination.
