joining our round table, stu trevelyan whose group ask called ngp van, he works with democrats, also joining us is chuck defeo of the republican national committee where he serves as chief digital officer and shane d'aprile. let's begin with you, mr. terrell january, if we could. -- trevelyan, if we could. what exactly are the components of a digital campaign? what type of tools are used? >> guest: well, so i think it's actually evolving. i think historically the digital tools were largely thought of as the e-mail tools and the online contributions, the web site, but i think it's evolved. our company, for example, also offers tools that enable sort of the shoe leather side of the campaign, so the canvassing, the phone calling, the direct mail. and then i think you're seeing many more marketing channels come online where now there's person addressable tv ads, online ads, you can actually do person addressable interactions through social networks, so i think now there's a pretty wide swath of things which you could call digital. >> host: chuck defeo, anything to add to that answer? >>
