Although McCain likes to call us - all of us - "my friends", he doesn't really have that many friends, does he? So it's not surprising that McCain grabs closely anyone who shows the slightest interest in him.
But what is Samuel The Unlicensed Plumber Wurzelbacher's motivation for hanging around McCain, endorsing him and going out to stump for the downward spiral? It turns out it's got nothing to do with politics, and everything to do with trying to launch a career as a country musician:
On Tuesday, Wurzelbacher joined country music artist and producer Aaron Tippin to form a new partnership that includes booking-management firm Bobby Roberts and publicity-management concern The Press Office to field the multiple media offers he’s received over the past few weeks.
Less harmless than Palin's motivation (a 2012 run in her own right), perhaps, but it must be heartbreaking for McCain to realise that his expensive presidential bid is running out its last few days as the poor man's American Idol.
