I don't claim to have a reliable methodology for predicting the outcome of political elections -- for those I defer to William Stickevers. Using the findings from my independent research linking political ideology to astrology, however, there seem to be a number of factors suggesting that the nation of France will veer conservative over the next decade. These factors appear to be stronger than similar factors which have suggested a libertarian/conservative turn for the US.
These are transits/progressions for France for today.
Transiting Pluto opposite France Moon (ruler of France IC): extreme changes to culture may be afoot. Note that France has had massive Islamic immigration for decades. "Multiculturalism" is the status quo and therefore is now subject to change?
Progressed Pallas approaching France Sun/Mercury: this is a waxing libertarian vector, similar to but stronger than the one the US has been under.
