Mexicans will go to the polls to choose a new president, new senators and federal deputies - and if opinion polls are to be believed, possibly a new governing party.
A major election issue is the country's crackdown against organised crime which is now in its sixth year. It has caused violence to flare in states that are on the drug route to the US and more than 50,000 people have been killed since 2006.
