The Poker Term for this a "Tell"

The fact that the Texas Attorney General is threatening to arrest international election monitors if they monitor elections would appear to indicate that he knows that his fellow Republicans are :

The Texas attorney general, Greg Abbott, has threatened to arrest international election monitors invited by liberal groups to observe the conduct of next month’s presidential vote in states accused of attempting to disenfranchise minorities.

Abbott has written to the Organisation for Security and Cooperation in Europe warning that its monitors have no right to monitor the vote even though they have observed previous US elections.

“The OSCE’s representatives are not authorized by Texas law to enter a polling place. It may be a criminal offence for OSCE’s representatives to maintain a presence within 100 feet of a polling place’s entrance,” he said. “Failure to comply with these requirements could subject the OSCE’s representatives to criminal prosecution for violating state law.”

They are trying to cover up their voter suppression efforts, though I'm sure that they there is a bit of anti-UN whack job paranoia in the mix.
