I know what you mean, but I Can Imagine it.I can't imagine the GOP voting for any Democrat in this current climate. The party politics won't allow it unfortunately.
It's like if it gets so bad that they have no choice.
Also they don't All have to vote for a Dem. I'm a little foggy on the math but I think if all the dems vote one way, than they just need 4 or 5 republicans to vote their way.
You might wonder if there are 4 or 5 Republicans that have enough backbone to vote that way and there isn't. Maybe 2. but there are a lot of terrible corrupt Repubulicans who have little conscious and no loyalty. I'm thinking the Democrats could either bribe them or blackmail them.
How about something like, we won't run anyone in your district if you vote for Jeffries.
Or the first 5 guys to vote for Jeffeies gets a million dollars each.
