Send a "message" to the GOP- what's the most effective way?

Trumps popularity is big because we're all fed up with the Political correct bullshit and status quo, so I still feel compelled to tell the GOP why and send them a message.
Would welcome any ideas on most effective way to flip them the bird.
Maybe daily emails with "trump" as the subject line and no text, sent by thousands would get their attention.
(I am not a political operative= whatever, just fed up)
