She is currently representing a district which includes Tucson and surrounding area. Raul Grijalva has gerrymandered the more leftist elements into his district but the district is dominated by Tucson and leans left.
It's very liberal and very closely divided so in order to win elections she needs to ride a fine line.
I suspect that she is more conservative than many people think and this may show in a statewide race.
Regardless, she is still a very good candidate.
The civil war that the Republican Establishment is fighting against it's base is very destructive and the more centrist Republicans in tough purple districts are seriously at risk of getting massacred in the next election
We need the liberal republicans to get massacred in the primaries, and put up only conservatives that represent US, not the rino republican establishment.
The only way you could consider McSally a good candidate is if you favor losing the country through amnesty.
