result of all left political families on all elections since the beginning of the 5th republic.
Considered as "left" all parties wich admitt themselve this qualification. Considered too, ecologists from 1974 to 1994 (and the division of this family between two wings). After 1994, only LV and EELV are considered as left.
translation france/US :
presidentielle= presidential
legislatives = congressional
regionales=gubernatoral
cantonales= dunno. County election ?
europeennes = election for european parliament
based upon those stats, I think again and again than the victory of Hollande would certainly not as easy as french polls are saying right now.
(and I don't speak about the so important legislative election of june)
I highly doubt the issue's that black and white.
