This came to my attention this morning: 
Now, just to make the best "apples to apples" comparison, I went to Gallup and found out what each man's approval numbers were for their 22nd quarter of their time in office, which falls in this time frame.
Bush had a 38.5% approval rating, while Obama had a 43.2% approval rating. Counting the days between January 1st and August 31st, there are 243 days. Dividing that 243 by the number of reports, we find that Bush averaged a report every 2 days (actually just a hair under at 1.95), while Obama rated one report every 27 days. Again, my math shows that for every report on President Obama's approval rating, almost 14 reports were made on President Bush's rating. I do not have the time to go back and check out all 133 articles to see what the tone and emotional indexes were for each one, but I'd be willing to bet dollars to doughnuts most (if not all) of Bush's articles were of a negative tone, while Obama's were at least neutral, if not positive toned. Despite all of the hammering on Bush (at that 14:1 ratio) his job approval rating was still only 5% lower than Obama's. And the Mainstream Media wonders why they have a big credibility and integrity problem.
