In this example, Obama cites historical precedent and economic data from past years to strengthen his argument that recent progress has been substantial and that the nation's economy is in good health:
"But tonight, we turn the page. Tonight, after a breakthrough year for America, our economy is growing and creating jobs at the fastest pace since 1999. Our unemployment rate is now lower than it was before the financial crisis. More of our kids are graduating than ever before. More of our people are insured than ever before. And we are as free from the grip of foreign oil as we’ve been in almost 30 years."
The above is an example of what rhetorical appeal?
