Where egos dare: Manchin and Sinema show how Senate spotlight corrupts

The two Democratic senators chose to wreck American democracy, simply to feed their sense of their own importance

What can possibly explain Joe Manchin and Kyrsten Sinema's decision to sink voting rights protections? Why did they create a false narrative that the legislation had to be bipartisan" when everyone, themselves included, knew bipartisanship was impossible?

Why did they say they couldn't support changing Senate filibuster rules when only last month they voted for an exception to the filibuster that allowed debt ceiling legislation to pass with only Democratic votes?
