While waiting for more results from this tight Super Tuesday (my friends outside the US, you have no idea how complex in the name of complexity is all this process!) lets watch a bit of history.
Take a look at this ad from the 60's. While it may not be creative for its content, it is surprising nevertheless. Yes, is Jackie, and yes, she is speaking (reading?) in Spanish, campaigning for her husband!
Her Spanish may not be really fluent, but... who else was (in 1960!) addressing the Hispanic voters IN Spanish?
PS: If you are interested in comparing this piece of history with the ads in Spanish for this campaign, you can find here an article with links to almost all the Spanish ads for the 2008 primary.
