What the polls say about a Biden v Trump matchup
(The polls say yeah so... yeah. Admittedly this is a repeat of 2016 and Ukraine will basically be the same thing as Clinton's emails and nothing is truly guaranteed.)

Can Biden beat Trump? The truth is he's just as risky as Bernie
(Neither of them is a guaranteed win. If there was a safe choice, it wasn't one of these 2.)

Stop saying Biden is the 'most electable'. Trump will run rings around him. (No. And not because of his record or gaffes, but because he is an establishment politician and Ukraine will leave the same impression on Biden as Clinton's emails. Are you people insane? Have you forgotten 2016?)

Fears grow over Nevada caucus malfunction (Probably as bad as Iowa. Not paywalled)

Another caucus is coming. But Nevada will look completely different (It will be far more representative than Iowa. Also they will use a Google Form so technical issues will be limited. Paywalled)

What we know (and don't) about the Nevada caucus 'tool' (Covers on the 'tool' that will be used to count the votes, potential backups in case of failure and a few other caucus related technicalities. Not paywalled)
