I think you have either confused your candidates, or your voters.  You said:

This seems to be about 30% of his votes, they think he's the Messiah. Granted a smooth talker, who really appeals to undereducated folks.

That doesn't seem to be the case.  Sen. Obama is actually doing better with the more educated voters, than Sen. McCain.

"...among those whose top educational qualification is an undergraduate degree, where Bush led by 6 per cent in 2004 but Obama leads by 11 per cent today. Even if Obama has not done as well as he might have hoped among less-educated voters, he has more than offset this by his appeal to the college-educated, who make up 75 per cent of all US voters."

"But Mr McCain's chief pollster, Bill McInturff, issued a memo this week, arguing: “All signs say we are headed to an election that may easily be too close to call.” He said that expected gains for Mr Obama among black and young people would be offset by increased turnout among rural and less-educated voters. “Wal-Mart women” with no education and household incomes below $60,000 (£36,400) are “swinging back, solidly,” he claimed.

I absolutely detest refundable tax credits... it is a form a welfare and they ought to just call it what it is.  And, I would agree that concept seems to resonate with the poor, who are generally less-educated.  But, many of Sen. Obama's plans for the economy make sense and that seems to be resonating with the college grads.  Both candidates have particular positions that many do not agree with, but you can't narrow your view to a single issue.
