Yep, that is the news I was hearing about.
This is likely to be minimized by my friends and brethren on the left, but this is the best possible development that could have happened to Graf this week short of Gabby getting caught sacrificing puppies to the Harvest Moon (and if I were the state Democratic Party I would point out that we have no evidence to suggest that she hasn't been doing this for years.)
There is no more respected and popular politician in power in Arizona than John McCain. Love him or hate him, you better respect him. He brings tons of independent and dare I say "squishy Democrat" appeal. The beauty of his endorsement is the single group of voters who are the most likely to discount McCain are already solidly behind Graf, and aren't going anywhere.
It also blunts and almost erases any sting from Kolbe's refusal to endorse Graf. After all, McCain and Graf are supposedly polar opposites on what many would consider their signature issues at this point, yet McCain is saying that everything else matters more. Kolbe could never single out what it was about Graf that made him unsupportable. Again, this endorsement highlights Kolbe's pettiness and makes him irrelevant.
This gives Graf supporters a response to those Republicans and Independents who have been led to believe that Graf is too extreme, but are leary of voting for a Democrat. There are more than enough of these voters to win the election for Graf, and nearly all of them are McCain supporters.
Finally, it is a good move for McCain. The people lining up behind Graf are the same people who would be most likely to fight a McCain presidential run. It would be very good for McCain to be able to point out who was there to help Randy Graf and who was not when the chips were down. If Graf were to win, this example would be valid nationally, especially if it were to save the House from being turned over to Democrats.
Now it would be icing on the cake to get some type of recant from Jim Click and Steve Huffman to go along with this endorsement. Especially if it were to take place before the debates.
