The subject line said it was LIKELY that Carson would drop out, which isn’t the same thing as saying he DID drop out. Everybody knows it’s likely that Carson will drop out; we just don’t know when.
So, you're saying the Subject might as well have been "The Sky is Blue"?
No. "Perhaps as Soon as Tomorrow" is clearly implied, especially when read in the context of the body of the message.
The Subject, "Carson Likely to Drop Out" motivates the recipient to open the message. Read the rest of the message, and the email's intent is clear.
I'm not saying it wasn't an honest mistake, just that it's wrong for Deace to claim the email "said exactly what these news reporters were saying."
