Poor Barack Obama’s grandmother.  She may never ride public transportation again.

Not after the beating — actually, tossing — she got following her grandson’s speech on the Rev. Jeremiah Wright.

You’ll remember these words from Obama:

“I can no more disown him than I can disown the black community.  I can no more disown him than I can my white grandmother – a woman who helped raise me, a woman who sacrificed again and again for me, a woman who loves me as much as she loves anything in this world, but a woman who once confessed her fear of black men who passed by her on the street, and who on more than one occasion has uttered racial or ethnic stereotypes that made me cringe.  These people are a part of me.  And they are a part of America, this country that I love.”

Since that speech, observers agree on one thing — Obama’s white grandmother got pushed under the bus.  Again.  And again.  And again.  Taking over from where throwing momma from the train left off, grandmothers and motorcoaches are now front and center.

In fact, buses may not have gotten this much attention since Keanu Reeves tried to save one in “Speed.”

Consider …

•    Ann Coulter:  “Obama felt perfectly comfortable throwing his white grandmother under the bus”
•    Gateway Pundit:  “Barack Throws His Ailing Grandmother Under the Bus to Score Political Points”
•    Powerline: “Throw grandma under the bus”
•    Rich Lowry: “The Throw Your Grandmother Under the Bus Speech”
•    Fred Barnes: “What he did, was throw his grandmother under the bus.”

Ah, but those are conservatives, you’re surely saying.  Hardly evidence of vehicular manslaughter, right?  And that crowd probably already hates buses, just like they presumably detest light rail.

Then you need to check out the message board of Obama booster Oprah Winfrey.

If you’re not moved to emotion by this comment, “Poor Grandmother, I hope there’s plenty of room under that bus, it’s getting kinda crowded,” then surely this one will grab your heartstrings, “He threw his grandmother under the bus while trying to extract himself from under the wheels. What a pathetic grandson, that Obama.”

And to think, those are the folks who scream and cry uncontrollably over a free car giveaway.  Must be the mode of transportation.

Even Oprah couldn’t save Obama’s grandmother from the bus as its big wheels keep on rolling.  So before we get out from under the bus, Gus, let’s make a new plan and hope Obama’s great-grandmother got better treatment.

Until then, we’ll have to ponder this question asked at Yahoo! Answers:  “Why did Obama throw his grandmother under the bus?”
