Katie Couric's Notebook: The Debate

Last night the presidential candidates lobbed information missiles across the table - but how many of them were on target?

John McCain blamed the housing crisis on lending practices at Fannie Mae and Freddie Mac. Not quite. They don't hand out loans to home buyers, they buy mortgages from banks.

Then, Barack Obama said 100 percent of McCain's ads are negative. That was only true for one week of the campaign, and both have spent more money on negative ads than positive ones.

Despite McCain's assertions, experts say Obama's health care plan would not hurt small businesses. On the flip side, they say McCain's $5,000 rebate would be enough to offset the tax burden from most employer-based insurance plans.

Do those health plans cover aspirin? It's all giving me a headache. It's no small task to memorize all the numbers and regurgitate all that information at a debate. But as Mark Twain said, "When you tell the truth, you don't have to remember anything."
