Arlen Specter is a joke and so is the two-party American system.
It is clear that when Pennsylvania voted for Obama and that democrats were gaining a significant majority in representation, Specter, who is near re-election, is keeping his interests in mind, keeping his power.
This whole matter of “representing” one’s views, values, or beliefs are just two-faced promises that are broken and fuel the fire of Washingtonian politics, that is, doing whatever is necessary to keep power and push agenda.
If our politicians actually believed in what they fought for, even if they happened to be dead wrong, but actually believed in what they were saying, then you wouldn’t have senators like Specter switching from party but switching from belief and values.
Parties in America are factions that hinder and hurt the process of democracy. It is when one power grows too strong that the other seeks vengeance and it is this that fuels the cycle of noncooperation.
As President Obama said, we are not democrats, or republicans but the United States of America.
