Implied in the blue wave arguments is that the democratic party is a cohesive group with shared ideals. Nothing could be further from the truth. The Kavanaugh confirmation may illustrate that point. Many democrats are pro abortion, but many will vote to confirm pro life Kavanaugh. Kavanaugh is very pro business, while the democrats are supposed to be pro worker – but many will vote for confirmation because it is good for their election, not the party. We see the same in immigration, banking, et. al. Even if the democrats get the house, my guess is that they will squander the majority with infighting.
