Now you are lying about what you have said. You said "Palin imploded in October." Unless you were assigning McCain's loss to Palin your statement makes no sense.
No what I’m saying is that McCain was already losing to 0bama.
Then he picked Sarah Palin and he was beating 0bama.
Then Palin imploded in October and McCain went back down to where he started before picking Palin.
So Palin had the potential at one time to attract more voters than 0bama, but that deflated as the public got to know her better.
Is that “causing McCain to lose”?
I don’t think so.
I think it means that despite all the hype, she just wasn’t able to help him win in the end.
