You assume that any state’s GOP is “trying.” LOL.
It all comes down to Conservatism.
If you do not support Drain The Swamp, then you are not Conservative. And if you have been in Washington more than, say, 10 years (note this is LESS than 2 Senate terms), you do not support Drain The Swamp and you are NOT Conservative.
Conservatism is Build the Wall, Drain the Swamp, America First In ALL Things, Pro Life and Pro Gun. Any deviation at all renders the individual not conservative, especially the 2nd item.
