Im a little confused by this. Are you saying that you reject the notion that Manchin statistically votes more often in favor of the Democrats positions in any given vote than a Republican would? Is it your view that a Republican in his seat instead would not vote any differently that he does? Or Is your view more abstract, say, that Manchin, for example, leaving the Democratic party and joining the Republican party will benefit the Democrats more than him staying because it would remove the baggage that the mantle of "having the majority" places on the Democrats? Is the benefit that Democrats get from that an expectation that they will be looked upon more favorably and/or voters will be more motivated to give them an actual majority and less likely to be critical of their failure to live up to expectations? Or is your position even more abstract?... something like an observation that Manchin, regardless of his statistical voting record, is not helping with the big ticket, more important items, and what he does help with is not really that important in the big picture?
