But it’s not what you think.  Politico reports.

For seven weeks this summer, staff members of the political action committee coordinated their efforts on behalf of Miller from staterooms aboard Holland America’s M.S. Amsterdam, a cruise ship that plied the waters from Seattle to various ports-of-call from Canada to Alaska. There, while other passengers were shopping or photographing glaciers, Tea Party Expressers held press conferences, rallies and meetings with Miller supporters. Between stops, they used their time at sea plotting strategy and cutting radio ads that they downloaded from a digital recorder and emailed to a studio for production.
