They don't care about killing their own voters or anyone else since a) they're sociopaths b) they and everyone close to them is vaccinated and has the best health care taxpayer money and frozen fish fiefdoms can buy c) they will likely successfully gerrymander / install lackeys at various steps of the election infrastructure d) if they can prolong the pandemic enough and wholesale shift blame to Biden for the case numbers and deaths, they can probably pick up enough dissatisfied "independents" to make up any difference.
