JD Vance believes the Republicans should nuke the filibuster now because the Democrats surely will the next time they have the majority. His evidence? The only reason we still have the filibuster is Joe Manchin and Kyrsten Sinema refused to vote with the rest of the Democrats to nuke it. As a result, they both had their careers blown up. Vance believes the other Democrats have seen that example and won't want to lose their own careers. Vance is probably right. 

This is another option.

Modern legislators seem to like anything that requires little effort from them. 

Honestly, the modern Left gets more and more vindictive and nasty, so they likely will nuke the filbuster as soon as they can. 

Republicans need to have a clear plan for what they want to accomplish if they indeed nuke it.

They must agree on priorities and get it done before midterms to make it worth it.
