Are AZ conservatives going to let this influence them? I highly doubt it. They're going to see it for what it is and continue to support Hayworth nonetheless.
McPain certainly didn't do much to support her; nor should she compromise her principles as “pay back” for a failed RINO run as VP.
Where is she compromising her principles? Just the other day she endorsed a grassroots conservative to oust David Obey here in WI. I too, was initially upset that she said she was going to endorse McCain, but it is what it is and it's something not to linger over. As long as she doesn't support other McCain cronies.
If you see Sarah Palin’s policies as the same as McPain, then by all means, she isn’t compromising on her Populist principles. Most people see Palin having little in common on ideology with McPain. If she can be so agreeable towards McPain, then whe’s worse than a Populist and another RINO in drag.
