The White House welcomed the cutest little popemobile

And The White House itself was dressed up in style

Presidential hopeful Bernie Sanders took his grandchildren house-to-house, but didn't wear a costume

Hillary Clinton got in on the Halloween action, but went sans costume as well

Rand Paul tried for something scarier than a zombie, but might have been a little too earnest

In Canada, Justin Trudeau dressed up as Han Solo (in a parka!)

And Donald Trump dressed up like an angry old man. (Or maybe that's just how he looks?)
