Why?

Texas filed a lawsuit to block the electoral vote certification process in other states — on the grounds that the voting processes in those states did not conform to what the legislatures of those states had required under the law.

Meanwhile, Governor Abbott of Texas authorized the use of ballot drop boxes in Texas — in direct violation of Texas law — for the same 2020 election. So by the standards laid out in the Texas lawsuit, TEXAS should not have had its electoral votes count in the 2020 presidential election.

This is one of many reasons why the Texas lawsuit went nowhere. Look up the common law “doctrine of unclean hands” to see how this works.
