There are a couple of reasons the republicans should absolutely nominate and vote on a new justice as soon as possible:
1. They cant look like they are beholden to the threats of violence from the left if they were to vote - not having a vote would make them look incredibly weak and feckless
2. The possibility of the need for a judicial ruling with the upcoming election and only having 8 justices would be a disaster
3. Ask yourself, what would the dems do? Of course they would push someone through
4. The dems behaved like assholes with Kavanuagh
5. The dems installed the nuclear option under Obama - lets hoist them by their own petard.
