I Thought That This Only Happened With Israeli Politicians

First Joe Lieberman went from Liberal Democrat to Republican, and now Arlen Spector went from Republican to Democrat.

In Israel, politicians play these games all the time. Of course, in Israel, you have so many more political parties, with new ones starting at a rather frequent rate, that a hyperactive politician can never really run out of options. And if he's bored, he can always start his own like Ariel Sharon did, more than once.

Arik, never known to do things by "halves," first established Shlomtzion and then Kadima.

Chanan Porat was torn between Mafdal (National Religious Party,) National Union and T'chiya. Finally, he left politics.

Of course, American politicians have only two and a "half" parties to choose from, which makes American politics more boring.
