Marco Rubio is differentiating himself with technology and music, but he's not entirely successful. The U.S. Republican from Florida may have a edge in the presidential campaign because he's just 43 years old, considerably younger than Hillary Clinton. 

PR Daily tells us how Rubio is showing his tech-savvy side on social media: 

The Florida senator's youth-focused approach isn't limited to rhetoric, either. Social media is a huge part of his campaign. For instance, staffers live-tweeted his Monday speech. Tweets and Facebook posts counted down the hours to the announcement. One tweet played on young viewers' love of the HBO series "Game of Thrones."

He's also joined Snapchat and created an emoji design in a tweet. 

He's also using contemporary music, such as "Something New," by the Swedish group Axwell ^ Ingrosso, but the band isn't happy about the association: 

"Axwell ^ Ingrosso didn't give their permission for this song to be used and don't want to be affiliated with a particular party during the upcoming presidential race."

Discussion Starters: 

• Someone tweeted: "@marcorubio STOP." Do you agree or do you find this campaign approach effective? 
• What, if anything, should Hillary Clinton do in response?
