Thousands of registered voters live outside the borders of the United States, who vote in State and Federal elections. Neither Congresspeople nor the White House recognize this fact in their forms, whether paper or online.
No form allows any "state" to be filled if you don't live in one of the 50; no "zip" allows any but the American Zip Codes. If you tried to donate to the recent Presidential candidate who now resides in the White House, your credit card, if it didn't come from a U.S. bank, was not recognized.
Most congresspeoples' websites are the same way.
Stop disenfranchising U.S. voters who don't live within the continental boundaries of the U.S. or one of the 50 U.S. states!
