particularly in text messages
That's because the system has been defectively designed, making typing in Polish extremely clumsy and time-consuming. Try to wirte the word ćmą (ćma/moth in the instrumental case) on a texting device for instance. If they can't have separate keys for the Polish letters as comptuer keyboards do then at least someone should have thought of including an ALT GR key to accent the applicable letters.
By 2015 PO will be down around 15% like SLD and PiS will be up around 45% or better. An enfeebled PO might join PiS as a junior coalition partner. That's how it was supposed to be in the first place. But the 2005 election shock suffered by PO made them bitter and vindictive and incapable of any meaningful
cooperation. Hence the exotic PiS-LRP-Samoobrona coaliton -- a loveless marirage of convenience. And then there was PO's all-out anti-PiS campaign. Like schoolboys, the Platformers wanted to put down and score points agaisnt PiS. If PiS said water is wet, PO would counter that it is dry, etc, etc. ad nauseum.
How long will they continue waging the Polish-Polish war? Probably it won't end until Tusk and Kaczyński bow out.
