I also approve of the New and Improved Lindsey Graham and, like you, I’ll need to see a sustained consistency in that improvement along with some select policy revisions over his past choices.
For now he has become a pretty good gun hand for Pres. Trump.
The consistency he has shown has been to consistently support every attempt at abandoning the rule of law and surrendering the country to illegal aliens with amnesty in 2006, 2007 and again in 2013.
