A new Mitofsky national survey confirms the continued shrinkage in the PRI’s lead in the July congressional elections. Their advantage over the PAN shrank to 5.5%, compared to 8.9% in February and 12.9% in December. More than one in five respondents (20.9%) are still undecided, but this is down from one in three last year.
The PRI still has the advantage in terms of committed supporters, who say their mind is made up, but the majority of supporters of all three major parties are “soft.” One third of respondents consider themselves independent.
The survey also highlights the differences in regional support. The PAN is strongest and the PRI weakest in the Bajío region. The north is basically split between the PAN and PRI with the PRD not a factor. The PAN is weakest in the southeast and center (where it runs third). Only the PRI has a clear nationwide base.
