MSNBC's Shuster claimed "[c]ampaign financing ... could help McCain tarnish" Obama -- did not mention McCain may be breaking campaign finance laws

SUMMARY: MSNBC's David Shuster asserted that "[Sen. John] McCain also made clear he will continue to insist that Barack Obama stay in the public financing system for the general election as he promised," adding that the issue "could help McCain tarnish the image of Obama's political purity." But Shuster did not mention that McCain may be violating campaign finance laws by surpassing spending limits under the public financing system for the primary period.
