My argument is that the original article expounded a complete misreading of the American electorate. My evidence: the great Blue Wave of 2018 in the House consisted of moderate to conservative Democrats flipping seats held by Republicans. Left Democrats won safe seats after winning primaries. To the degree Democrats move left on a national level, they will leave a huge pool of moderate voters who will not vote for them. Against a Resistance Left Democratic candidate, a third party candidate could do very well and relegate the Democratic party candidate to a distant third place in ten states or more. Is that an unrealistic prognosis?
