The top line, "Not Left. Not Right. Forward." kind of reminds me of Macron's "En Marche" ("Let's Go") that took over France in a storm, taking over the presidency AND the parliament only one year after its foundation, with very few previously known political figures in its ranks.

I suspect a huge part of Macron's success was his opponent. France elections have a top-2 runoff, and I wouldn't be surprised if many electors were like "I don't like Macron but I really don't want Le Pen to win".

That's Democrats, who almost always win the popular vote but are structurally handicapped by the votes for Senate and Presidency given to rural states.
