poli-fluential
n.—Gloss: a person who is actively involved in influencing others about their political points of view. Note: This brand-new term is untested and joins the oodles of words coined by political marketers and analysts, most which fail to catch on. You can read the report from which it comes here. «They call these people the “poli-fluentials” and differentiate them from people who are merely “influentials” (defined as someone who sometimes e-mails public officials, writes letters to the editor, calls a radio show, goes to a rally or joins an advocacy group) and people who are “politicals” (defined as someone who donates money to or volunteers for campaigns). Poli-fluentials, IPDI finds, do both kinds of activities.» —“’Political kingmakers’ take to the Web” by Andrew Rasiej, Micah L. Sifry Politico Oct. 10, 2007. (source: Double-Tongued Dictionary)
