What if the only way to save America from the Fascists was a Conservative/Liberal coalition...?

51. As I stated BOTH Kerry and McCain rejected the idea as unworkable

Here, you seem to ask the Democratic party to go beyond even the centrist positions needed to get 50 Democrats and no Republicans. It is likely that the parties both are always close to the same size in terms of very committed partisans. What changes is motivation to vote and where the non aligned go.

Now consider the 2 pieces you want to combine. The Democrats alone have a good chance of winning. The conservative non Trump people might be at most 20 percent of all Republicans, which may be generous.

What does the presumably Democratic Presidential nominee have to promise to lead a liberal/conservative coalition? No improved social programs like childcare, improvement of ACA, ... No proposed tax increases for corporations or the top 1 percent? The president will not push Congress to codify things like Roe v Wade or LGBT rights? With the current polarization, there are huge areas with no viable overlap.

Now, consider what percent of liberals we lose because we have disheartened are key voters.
