During a recent interview Palin was asked "what kind of hockey mom were you?"  Her response was quite telling:

I was the type of hockey mom where until my son told me 'enough no more' I'd go down there banging on the penalty box glass telling him I said 'you be nice out there...


I was telling him 'be nice' if you're going to get a penalty man make it worth it. Don't just be picking on somebody.


You know grind them into the boards.  Do something that's going to be effective, don't just be picking on someone.

See her response at 2:45 mark of the video:

According to Wikipedia, checking someone into the board is "usually not allowed in amateur leagues and leagues with young children."

But I'm not here to judge whether such advice is unsportsmanlike.  What fascinates me is how Palin's hockey experience can shed light on her recent aggressive attacks against Obama:

With his electoral prospects fading by the day, Senator John McCain has fallen out with his vice-presidential running mate about the direction of his White House campaign.


McCain has become alarmed about the fury unleashed by Sarah Palin, the moose-hunting “pitbull in lipstick”, against Senator Barack Obama. Cries of “terrorist” and “kill him” have accompanied the tirades by the governor of Alaska against the Democratic nominee at Republican rallies...


Palin, 44, has led the character attacks on Obama in the belief that McCain may be throwing away the election and her chance of becoming vice-president. Her supporters think that if the Republican ticket loses on November 4, she should run for president in 2012. 

Palin is probably telling McCain the same thing she used to tell her son:  Stop picking on Obama on the issues.  Make your attacks count.  Talk about abortion, Ayers and Wright.  Grind him into the board John.  Grind him into the board!
