Word clouds of the candidates' acceptance speeches show how often they use certain words.

A side-by-side comparison of the most used words in Romney's speech last night (left) and John McCain's 2008 acceptance speech (right) reveals the Republican Party's consistent emphasis on business and jobs. 

"The choice of words is very similar between 2008 and 2012. Jobs and the economy dominate both acceptance speeches,  however the context is very different," said Duke political scientist John Aldrich, an expert on political parties.

"McCain's language was defensive and attempting to separate himself from the Bush administration.  Last night Romney centered his speech in contrast to the Obama administration, and was, because he could be, more positive and assertive.

"While both had a second theme that included family and country, Romney's theme was an even sharper focus on family.  He has established a campaign theme of economic improvement to help families."
