Republican Arizona Gov. Doug Ducey was allegedly reluctant to appoint then-Rep. Martha McSally to the Senate at the end of 2018, and now his fears over whether the Republican could hold onto the late Sen. John McCain’s seat two years later are being realized.

Now-Sen. McSally is trailing Democratic challenger Mark Kelly by 13 percentage points, with the retired astronaut and former Navy captain extending his lead over the incumbent by four points since April, according to an OH Predictive Insights poll released Tuesday.
