Folks like to criticize Randy Pullen for taking on the Congressional delegation but he occasionally pulls a punch. Here's quote from an interesting article from the London Times that details McCain's troubles.
Randy Pullen, chairman of the Arizona Republican party, said: “He’s a battler, so I’d expect him to carry on, but everyone is waiting to see what his new fundraising totals are. That’s pretty critical. If he doesn’t have the money, he won’t be able to run.”
I think that's a fair assessment. Immigration is discussed later in the article, but there's no mention of amnesty.
McCain is learning that the Gray Lady is a fickle mistress. You can do well with the intelligentsia if you turn against the base, but when you eventually acknowledge the party regulars, the New York Times crowd moves on to a fresh "maverick."
