1. There are no more "moderate republican politicians"
2. The center is which Biden resides is light years more "liberal" than where the current Republican party is hanging out.
3. Are there more liberal politicians out there than Biden, hell yes. But to say Biden is like a moderate Republican is sad.
4. And I can read quite well. You said the difference between Biden and a Republican is minimal. And don't hide behind that moderate tag. All of those moderates are either too scared to say anything about the current state of the Republican party, or they don't exist. And if Biden happened to find the lone remaining moderate Republican I would want someone with more backbone than the fence-sitting jellyfish that Trump has turned them into.
