Here’s the way I would put it.
To win leftist support, Talarico needs to persuade leftists that he is more left-wing than Ken Paxton which is really easy.
To win moderate support, El-Sayed needs to persuade moderates that he is more moderate than Rodgers — takes more effort.
centrist dems are more comfortable sharing power w former & current republicans than their left flank who'll pull the party further left. we don't oppose talarico & cynically lean into rw attacks in the way that liberal consultant do w/ AES. we don't make a big fuss abt pappas low performance in NH. neera tanden is here to undermine the left and doesn't care if left flank dems lose their races in the process. her output and focus on the left proves this.
