Mitt Romney has all but won the GOP presidential nomination -- and the endorsement of most of his former primary opponents -- but just when he thought he was in the clear, Romney ran into opposition in a rather unlikely place: Poland.

Ron Paul supporters were all over Romney as the candidate visited the country on Monday, showing up in town squares with massive pro-Paul banners and chanting Paul's name outside of meetings.

The Polish Paul folks didn't end up there by chance -- a group of pro-Paul Poles have been organizing on a Facebook group, Poland for Ron Paul. (Description: "Polacy wspieraj najlepszego kandydata na prezydenta USA!" Translation, according to Google Translate: "Poles support the best candidate for U.S. president!")

The page, which has 2,058 likes at the moment, hosts information in Polish about Romney's schedule, how to buy Ron Paul T-shirts and discussion of American political memes. The source of the Pole passion is unclear, especially since Paul is no longer actively campaigning for the GOP nomination and has never visited Poland.

Paul's office declined to comment on the matter.
