Every Republican in Wyoming needs to vote. Wyoming has open primaries and the RATS will be voting in the GOP primary. Any state with open primaries is asking for RINO takeovers. Texas is one of them with open primaries and we get the worst RINOs in the world elected because of open primaries.
There are not enough of them.
Cheney has split opposition in the primary as well. That would be her only path to victory - she could have the overwhelming majority vote against her but still win with a small plurality due to divided opposition. The voters need to unite behind one opponent.
