Jeff Flake. That race was shadowed by the death of John McCain, a towering figure who represented Arizona in the Senate for six terms.
Arizona Gov. Doug Ducey planned to name a replacement to fill McCain's seat after the primary.
Trump, who captured the battleground state of Florida by just more than one percentage point in the 2016 White House race, tweeted his congratulations to DeSantis after the victory and said he would be "a fantastic governor".
