Personally I wouldn’t vote for Phillips in a primary and for several reasons:

I think Biden is doing a very good job. Just one example, I’m really impressed with how he quietly built European support for Ukraine. Germany and a lot of other European countries have pretty substantial energy ties with Russia and they they went against their own selfish interests when they backed Ukraine and from what I’ve seen Biden was personally instrumental in that.

Also, I don’t think Phillips can build the coalition Biden did to defeat a potential Trump campaign. Hilary couldn’t. My district voted for Trump in 2016 but for Biden in 2020 and from what I’ve been able to see, based on voter turnout maps, that’s largely a result of increased turn out especially among black folk.

Piggybacking of that last one. In my opinion Trump represents an existential threat to American democracy. The election will be on November 5, 2024. If Biden dropped dead November 4th I’d still vote for him.
