Yes it is true. It is not a myth. It is not a lie. He was the one 'who could win', yes. Very few were excited about the prospect of his candidacy. I sure wasn't. There certainly wasn't an effort to draft him into the race. There certainly weren't thousands of volunteers signing up BEFORE he entered the race. There was no "Draft Bush" movement. There were no crowds chanting 'Run Bush Run'. There was no guy in the crowd at the Today show with a sign urging Bush to run.
Once bitten, twice shy. That is the truth.
No, that's your OPINION. And one that is formed on the basis of misinformation. Continue to dispute it if you like, but it'll only cement in people's minds that you see Bush, because that's what you want to see.
