Two things IC, by who's authority does BNG have a sling at others, threatening expulsion many times.
Politically IC, many original followers of Obama have seen by now the 'real' Obama. Recent tactics includes trips to foreign lands on his 'roadshow' hyping up the 'irish' vote, etc.etc.etc. Perhaps one day he will actually take the problems on that exist in his own country?
Another scenario is, who is going to replace him from the other camp? If Palin(she's gunning for it) is it, you might just as well stick your heads in the sand for another four years and watch the US disintegrate.
