i agree with ipa and tdaver that voting in a non-competitive state is entirely expressive, and one need not weigh any of the considerations with which voters in competitive states are burdened or privileged.
in several previous elections i've voted for presidential candidates i did not actually wish to win, because i thought it best allowed me to express the direction i would prefer politics to shift. i did that in 2016, and don't regret it.
in 2020, i voted for biden because the most important message i most wished to express is complete rejection of trump, trumpism, the lawless corruption, cruelty and incompetence that have characterized his presidency and the falsity of the incoherent and ignorant idea that both candidates and current iterations of both parties are in any way moral equivalents.
