The Left is in a bit of a quandary as to how to attack Cain and in "media" boardrooms across the country, I'll bet the subject matter of conversation centers around how to stop him. So, I predict the following:
If Cain continues to move upward and starts polling favorably vs. Obama, someone in the "media" or its parent organization, the DNC, will start to construct a narrative about Cain's history of cancer and fitness for high office. Their angle will be, "yes, he's in remission now... but what if it recurs... look how unstable our national situation is... is it wise to elect someone we know could die in office? After all, Paul Tsongas died of cancer just a few years after running for President in 1997."
Watch for it. It's coming.
They will stop at NOTHING!
NOTHING is too low for these people.
