Mexico ruling party wins Congress vote after rocky polls

Mexican President Enrique Pena Nieto's party retained its simple majority in Congress on June 7 despite his falling approval ratings and violent election day protests in several states.

Combined with its allies, the Institutional Revolutionary Party (PRI) could win between 246 and 263 seats in the 500-member lower chamber of Congress, compared to 251 today, according to estimates by the National Electoral Institute.
 
The elections, which included races for hundreds of mayors and nine governors, were marred by protests in southern states where radical teachers angry at Pena Nieto's education reforms burned ballot boxes in a failed bid to thwart the midterm vote.
 
National Electoral Institute president Lorenzo Cordova said that the overall election process was "positive" despite "incidents in certain areas."  

While the PRI and its allies held on to the lower chamber of Congress, a political shockwave loomed in the northern industrial state of Nuevo Leon.
 
Exit polls showed Jaime Rodriguez Calderon, a foul-mouthed rancher dubbed "El Bronco," will become the first independent candidate to be elected governor since a 2014 electoral reform, riding a wave of discontent against corrupt politicians.
 
"This will be a citizens' government in Nuevo Leon. Nuevo Leon will be the beginning of a second Mexican revolution," Rodriguez told supporters after a TV Azteca poll gave him a six-point lead over the PRI's candidate.
         
But nationally Mexicans kept the PRI on top.
 
Pena Nieto's party is expected to win between 29.87 and 30.85 percent of the congressional ballots, slightly less than in the 2012 election, according to the National Electoral Institute.
 
This would give the PRI...
