The Hinderaker Correction

With regard to the controversy that inspired a huffy post here, John Hinderaker revises and extends his remarks on conservative criticism of McCain:

Conservatives are of course free to criticize anyone they choose, a privilege I indulge in freely.
That's a 180 from this:
And if [conservatives are] going to sit it out, I'd appreciate it if they would sit it out entirely; in other words, stop attacking McCain for his "impurities."
Fine. We'll go with the more recent version.
