Can the Democratic candidate win the 2028 election while having to deal with attacks coming from both the right and the left?

Something I've been noticing for the past few election cycles is that along with fighting a growing right-wing misinformation and disinformation machine, the Democratic candidate and party have to deal with criticisms coming from the left.

When it comes to the right, it's clear that they have to deal with their own divide (Republicans displeased with how Trump has shaped the party). However, the attacks these groups make (like from the Lincoln Project) don't seem to cause that much schism in the Republican party or base.

Contrast that with the Democratic Party, where there's more criticisms and attacks than one can count. These range from Democrats and capitalism suck memes to left-wing YouTube channels dedicated to attacking the flaws of both parties but gives pointed criticism to Democrats to IRL protest movements that could potentially dominate an election cycle (or at least affect the narrative).

So, while the next Republican candidate will have to deal with attacks coming from the Democratic candidate and party, the Democratic candidate has to deal with attacks not only coming from the Republican candidate, party, and propaganda machine, but also from those further left.

As it stands right now, it's it possible to win an election while fighting both fronts, and are there ways to even the playing field so that the Democratic candidate can focus more on fighting attacks from the right?
