No, in all of the contested states where competing slates of Electors were submitted, the Governor of the state, be s/he Republican or Democrat, have in every single case certified the Biden slate of Electors. If the two houses do not agree which slate to count, the Biden Electors will be chosen by default.
Very questionable whether the Electoral Count Act is constitutional. The Constitution specifies that the state legislature has plenary power to award electors, yet the Act specifies that the governor is deemed superior to the state legislature if there is a dispute. Seems unconstitutional to me.
