Pena Nieto's Party In the Lead Ahead of Mexico Mid-Terms

A poll released on Tuesday shows that Mexico's ruling Institutional Revolutionary Party is in the lead ahead of Sunday's mid-term elections, potentially returning President Enrique Pena Nieto his razor-thin lower house majority. On Sunday, Pena Nieto faces his first national vote since winning the presidency in 2012. The lower house, nine governorships and various state legislatures are up for grabs.
