I just did a DuckDuckGo search on "President Trump's endorsement of Lindsey Graham for Senate"
This is the response:
"President Trump has endorsed Senator Lindsey Graham for re-election, stating that Graham has been a wonderful friend and is always there when needed. Trump emphasized that Graham will not let voters down and encouraged support for his campaign in South Carolina."
This is not a surprise. Graham is one of Trump's golfing buddies.
That said, Graham will sink or swim depending on what is happening in Iran on June 6. That is over two months away.
That’s good enough for me. My vote will go to Graham.
