(CNN) – Sen. John McCain is not letting the memory of Sarah Palin's recent visit to Arizona slip away. In fact, McCain is highlighting the former Alaska governor's two campaign stops in a new, fast moving Web video that promotes her support for his Senate re-election bid. McCain's campaign released a 1 minute and 37 second video Monday of Palin and McCain on the campaign trail – bringing back memories of their 2008 White House bid. Now, McCain is facing a primary challenge from former Rep. J.D. Hayworth, who claims the Arizona senator is not conservative enough.
