I think the Wall Street Journal had the best lede on this:
“U.S. intelligence officials have examined more than a dozen sightings of unexplained aerial objects that displayed no visible propulsion or that used technology beyond the known capabilities of the U.S. or its adversaries, according to a senior U.S. official describing a new report.“
Disclaimer: I work for BPI, who published the post above.
Also, this report from Wesleyan University is related and shows the same general trends. I would caution citing the data for specific races here as it pretty noisy data that relies on some assumptions.
As a Democratic political consultant who lived and worked in DC for years and has many friends who work on the Hill, I will tell you that this is exactly right.
Lobbyists do the same thing (target the staff), they just do it over coffee, lunch, drinks and/or briefing materials on a desk. 20- & 30-somethings run most of DC.
Yeah, seems pretty skewed right/conservative in the few bills I voted on. I have seen this phenomenon before, for example in Votizen, where a lot of well organized Ron Paul supporters are some of the earliest adopters of online political tools.
