Except that I don't think Obama will govern from the radical left. He is not so stupid. He will govern from the center left, slightly to the left of Bill Clinton. The only place you will see far left decisions is judicial appointments. For most Americans, this will mean very little change (as from Bush I to WJC), and so with his smooth rhetoric and media fawning, will easily win re-election. Obama is not going to call for a Socialist realignment of America. That is a non-starter.
So those hoping for an unleashing of radical liberalism from Obama will be disappointed.
And besides judicial appointments, the only other real change will be foreign policy. But most Americans don’t know or care about either. My point is, the damage will only become apparent in the long run. During his time in office, it will all seem fine.
