The election exacerbates the pain for both dems and pubs.
It showed that the dems can win in many areas but are saddled with a president who probably cannot and most dems believe they deserve better.
It showed, as discussed in earlier Harmeet Dhillon versus Ronna McRomney comments, that the pubs have no get out the vote plan and it will bite them over and over and over. Pennsylvania's voting begins 50 days before the real election. Pubs have no plan to deal with that and similar voting scams.
To be fair to the republicans, they have a harder get out the vote due to logistics. There are many democrats in densely populated areas and it makes their GOTV easier. Republican voters who aren’t regular voters tend to be in rural areas and it makes reaching out to them more labor intensive. This is not saying republican efforts would be for nought, just the ROI will not match what democrats can achieve.
Republicans, imo, are just stupid for not embracing vote by mail. This is the key for them to catching up.
