Scotland had a historic referendum on leaving the United Kingdom resulting in a narrow 55 percent vote against leaving the UK.And when the 55 percent is for Obama, it counts as a landslide. 55 to 44.x is not a narrow victory, particularly since the cooked books polling leading up to the referendum was pushed as showing a five percent margin of victory for what turned out to be the losing side. Silesia, an odd partly German, partly Slavic/Polish enclave stitched into Poland by the USSR after WWII, has been seeking greater autonomy, but the Polish government doesn't go for that. I would like to see it, but as with any of these, the majority in the geographic area are not in favor or couldn't care less.
Silesia belonged to Germany until 1945 when it was given to Poland—at the same time Stalin took large chunks of Eastern Poland (where much of the population was White Russian or Ukrainian). The Germans fled from Silesia and the area was resettled by Poles. If any Germans are there now they are probably not very numerous.
