As an American, my advice to the British and French left, center and center-right is simple. You have a duty to vote for the candidate that can stop the apocalypse of Le Pen and the hard Brexit of May. If you're left of Macron, this means shutting the fuck up about the "neoliberals" and your insane purity tests. Vote for Macron. If you're to the right of Corbyn, this means going out on a limb for leftist policies you might not be entirely comfortable with. Vote for Corbyn. We in America had a similar position as France currently is. The left failed to show up in the primaries, and so we were ended up with a centrist and a right-winger. Unfortunately, the Bernie or Bust/Stein crowd on our left wing spent twice as much energy reinforcing right wing/Russian propaganda to tear down Hillary Clinton as they did working against Trump. If you're a leftist in France and you're inclined to spend the next month attacking Macron, how's he's just as bad as Le Pen, and they're all neo-liberals, instead of focusing on Le Pen, seriously consider what you're doing. We in America failed and now Trump is dismantling a half century of liberal progress. You guys absolutely have to learn from our mistakes.
