Have you no shame, Mr. Novak?

According to Dave weigel/DailyKos the Republican National Committee's Martha Stewart-like relationship to truth has reared its ugly head again.
It seems that new DNC chair Howard Dean made a speech at Cornell University in which he said "if Social Security were left alone for 30 years, its benefits would be reduced to 80 percent of what it is now."
When this story was reported by Robert Novak on CNN, he changed it to say "Over the years it [social security]'s going to lose about 80 percent of the benefits."
Although David Brooks pointed out this discrepancy on MediaMatters on Feb. 28th the RNC website continues to repeat it as of this writing.
Perhaps the question really is: what will the Republican right-wing (redundant at this point?) not do to promote its agenda?
This must be the way Mr. Novakis carrying out the mission he describes in the latest issue of Vanity Fair:
"I'm trying to tell the truth and taking positions that I hope are godly positions, positions that I hope are helpful to my fellow man,"
