Remind folks that they lose 3% minimum when they use a credit card to support any particular candidate. Send a check to your favorite guy , at his “home” address, not Merryfield , VA, if you want he/she/it to get first crack at all the money. Trump’s only good address is “Trump Save America” in Kansas.
