HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!
Just another liar like McCain and Flake!
McSally's strategy is to divide the right and win.
From the story here:
Arpaio's presence in the contest might divide far right support and thus provide a path for McSally to win the nomination. ... In fending off a primary challenge in 2010, Sen. John McCain released a now infamous ad in which he promised to "compete the danged fence." [sic] But McCain and Flake both co-sponsored the so-called Gang of Eight immigration bill that passed the Senate but was anathema among conservatives, particularly those in the House.
