What on earth are you talking about?
No one has to do anything to "stop Keyes".
You make it sound as if victory is his to lose. Or rather, as if his victory is someone else's to lose "for" him.
Keyes himself knows he's not going to win.
This, like every other campaign he's run, is a "for show" campaign. A way to get some camera-time, some mike-time, some moments in the debate, so to speak.
Those people who characterized him as "our Sharpton" weren't making a joke. That is a clinical definition of his role in conservative politics.
Neither Keyes or Sharpton is going to win any election.
The big difference seems to be in the supporters.
Keyes supporters, it seems, really do believe that ne does run some risk of actually winning an election.
My advice?
If you are truly dedicated to the man's parade, then enjoy it for what it's worth, just as the Sharpton camp followers do with their party.
But don't give yourself ulcers over it, fretting about "someone" or "something" happening that's gonna make Keyes lose. You're looking down the wrong end of the kaleidoscope!
"I think it would be the best thing for this country if indeed we approach this the same way as we approach owning an automobile and took the steps that were necessary," he said. "You have courses that you can take and other things to reach minimal thresholds so that you can have access to this, that. As you wish to move to a higher threshold, you would take other courses until you could responsibly enter into them."
Whine about it to someone who cares.
