A Question of Momentum

Macario Schettino on the July 4 elections:

[T]he most important part of Sunday's elections is that it swung the momentum. The PRI advance turned out to be short-lived. It was, in reality, since last year, but it was hard to see. In 2009, the PRI achieved a great result in the mid-term election because of the confluence of two elements: the economic crisis and the null vote experiment. The first cost the government, which always happens, and the second had many followers among young people with high levels of education, which is a traditionally PAN constituency. That's why the PRI won a majority in the Chamber of Deputies, with it's now permanent ally, the PVEM. Not because the population was being converted back to them.
