On the right, we have:
* USPS sabotage and state-level voter suppression measures in urban areas leading up to the 2020 election
* Post-election soft coup attempt via the courts (including having broken precedent to rush a SCOTUS appointment during the election, which could have changed the outcome of the coup attempt in a different timeline)
* 1/6
* Ongoing propagation of the "big lie" and scheming to overturn the election (https://news.yahoo.com/bizarre-seven-point-plan-reinstate-14...), alongside continuing implementation of state-level voter suppression measures and gerrymandering
And the left has:
* Failed to advocate for open source voting systems (which isn't a widely known or politically relevant issue on either side at present)
* Pushed for stronger voting rights and increased voter participation — both uncontroversially positive properties of a democracy, but also happen to benefit the Democratic Party at the current moment
* Proposed measures in the For the People Act that were arguably overly ambitious or aggressive in the current political environment, such as stricter campaign finance regulations, which were promptly renegotiated within their own party ranks
To frame these as comparable is borderline gaslighting.
