I want the fachos to lose resoundingly.
@Sandra that's the thing -- even a 90-10 result in favour of Macron would not be a "resounding defeat of the fascists", because the fascists are also in Macron's team (Blanquer, Darmanin, Castaner,..).
This run off is fascist v. fascist
Now I do agree that Le Pen will be way worse (not just because she deals directly with neonazi militias) and I do hope she'll be denied the presidency.
But i also understand what @silmathoron is saying about the thinnest victory margin possible: a big score in the run off would be immediately spun by macron's team as a nonnegotiable mandate to carry out his policies, like it was for Chirac in 2002. This is also very dangerous, more so since Chirac maliciously synchronised both executive and legislative elections to happen simultaneously. Least bad outcome this year is a thin margin victory and a hung parliament.
