Here's Sen. Barack Obama answering David Letterman's question about possibly accepting a VP slot on last night's "Late Show":

To welcome Sen. Barack Obama on Letterman, the Republican National Committee released its "Obama's Top Ten Fabrications," playing off Letterman's nightly Top Ten list.

Going over the list, it's clear that the RNC needs to get a few more researchers on the Obama case. If it's humor you want, stick with Letterman, because the RNC list is very serious. But if this is the sum total of what Republicans have on Obama, then Democrats should be very happy.

For instance, the No. 1 "Fabrication" -- supposedly the top not-quite-a-lie of Obama's life? "Seeing a photograph in Life or Ebony magazine changed Obama's life." Apparently, neither magazine ever ran a photograph of the sort Obama described as life-changing.

If the RNC wanted to make a pre-emptive strike at Obama, then why not create a list of Obama's "Top Ten Liberal Views" or something along those lines?
