A much better idea would be for Freepers and others to send post cards to Schumer, Warren, and/or Franken saying “I will send at least $25 to your opponent in the primary and, if necessary, the general election. So, Resist That!”
I agree. Send cards to THOSE guys. If you send a postcard to the WH, it will get lumped in with the rest and make it look like they received more of those stupid #resist cards than they actually did.
