ANALYSIS
New PRI party President-elect Enrique El Guapo Pena Nieto will have to rely on 2 minor parties to get his agenda thru congress...the so-called Greens...and PANAL.
With them on board...the PRI could control half the lower house.
The Senate is problematic...and stiff concessions will be demanded by the conservative PAN.
He has refused to concede...claiming widespread 'fraude'...perhaps 5 million votes...and illegal campaign spending in the millions.
Officials won't make the election official...or reverse it...until 6 September.
