The Mexican cult of Santa Muerte today asked its followers to go to the polls on July 5, but that they vote for "candidates for teh next generation," that have a democratic vision and respect cultural, social, and religious diversity.

The leader of this religious group, of which it is calculated has more than 5 milion members in Mexico, David Romo, read a declaration in the temple in Tepito that exhorted the faithful to vote for those who respect ecology, for those who want to toughen laws, and those who offer equal justice.

In the opinion of the leader of the cult, not voting in the local elections on Sunday is like betraying or turning your back on Santa Muerte and shows a lack of respect for society and for the country.

"For the love of Santa Muerte go vote this Sunday and give an opportunity to the candidates who want to serve the people and demonstrate it with acts," said Romo in his statement.

Also, the archbishop asked that they don't vote for "openly Roman Catholic candidates and those who like to be involved in processions and go to mass" and that they avoid supporting those who only see the voters as "merchandise" or "clients" and then later forget about them.
