It seems like McSally's just spending a lot more money than the other two, which isn't surprising.
Anyway, Sinema vs McSally is certainly going to be a fun race because both of them have a record of flip-flopping and changing positions the way the political wind is blowing.
Martha "I support DACA" McSally vs Kyrsten "Prada Socialist" Sinema. Hoo boy.
I think Sinema is kind of overated. I think McSally can actually win. After all, Arizona has voted Democrat only once since 1952 in presidential elections (with Bill Clinton in 1996) and has not elected a Democrat at the U.S. Senate since 1988 when Dennis DeConcini won a third term. That's a long time.

So I think it could be an effective attack by McSally against Sinema whether it's in attack ads or on the campaign trail by questioning Kyrsten Sinema's foreign policy judgement and describing her as weak on terrorism.
