When did Trump endorse McSally???
About a week back. Look Trump knew that Arpaio was playing the spoiler role and had no chance of winning this primary. Had Arpaio withdrawn his name from the race Trump most likely would not have endorsed any candidate. But....Trump needs two dependable Republican Senators on his team.
With McCain passing on, Trump saw the opportunity to have both McSally & Ward as Senators. So...he endorsed Doug Ducey, the Governor and Martha McSally. Knowing that Both Ducey & McSally would win their races in the general election, Trump laid the groundwork to have Ducey appoint Kelli Ward to fill the remainder of the now passed on John McCain.
Senator, Jeff Flake (retiring)sought to throw a monkey wrench into the McSally effort by endorsing her...but, she wisely rejected his endorsement. Flake was in cahoots, IMHO, with the dead McCain to insure that one of the McCain family get appointed to take John McCain’s senate slot to give Trump pain. Both McCain & Flake were political gutter trash. McSally said to Flake ....no way, buster!!! Case Closed. I believe Ducey will be Governor, McSally and Ward will be Senators and Trump will be happy. End of story!!!
