Why?

You make these bold claims but you don't explain any rationale, reasons, logic, or facts to support your claims.

So for you the increase in the federal debt indicates the Presidential performance? That's an interesting metric to choose. Given that debt is compounding. The policies and debt obligations in place before a Presidential administration starts grow as the budget is raised each year. So, in Obama's case the high cost of military and wars continues to grow under his watch, even though he may not have made the buying decisions to result in that debt.

There are other metrics that improved significantly with Obama:

• Unemployment went down
• The stock market went up
• More private sector jobs were created under Obama's reign in 2010 ALONE, than in all of Bush Jr.'s reign
• Bloomberg ranks US Prosperity under the last 6 Presidential administrations, They ranked Obama's #2, second best out of the last 30+ years

Do you read facts?
