Is Hillary Clinton officially the Black Knight from Monty Python? How long are her supporters going to keep yapping about meaningless, uncontested 'victories' that do nothing to change the fact that she's already lost? Hillary Clinton: she'll bite your legs off!

Actually, she reminds me more of the subject of that Cake song 'Going the Distance':

"The sun has gone down and the moon has come up,
And long ago somebody left with the cup,
But he's driving and striving and hugging the turns,
And thinking of someone for whom he still burns."

I don't know who she's thinking of - assuming it's someone other than herself - but drive and strive as she may, the race is over. The cup is gone. That was a sweet little lap she just pulled off in Puerto Rico, but ... so what?
