Saying that there is no difference between left and right provides a juvenile excuse not to bother holding them accountable, assuming that it cannot be done. Such thinking is ironically, the ultimate in leftism, infantilizing oneself!!
That sounds nice, but in actual practice, partisanship such as that which you espouse has been shown to completely fail at holding either party responsible and accountable.
Instead of perpetuating your fantasy, you might try looking at some actual issues.
For example, take the issue of the Patriot Act. When the Rs were in power, Ds were foaming at the mouth over the Patriot Act.
When Obama became elected, Ds began to defend the Patriot Act, arguing that "we all voted for it at the time, and so did the Rs! It was necessary!"
Now, most concern about the Patriot Act comes from the Rs.
I'm aware this particular incident might be interpreted as a failure of Ds, but it's a classic example of something which occurs all the time. When the Rs are back in power (nationally), we will see them begin to do this with a slew of their pet issues.
In neither case did anybody elect to hold
their own side "accountable". In both cases feigned concerned over the Patriot Act was nothing more than an excuse to attack the other side. When it came time to hold their side "accountable" and deal with the issue, everyone chose to continue mindless partisan bickering.
Now, after having spent a long time detecting an insidious authoritarian undertone in your ostensibly pro-liberty positions, this surprises me little: like any closet statist, your real desire is to enhance the power of your "side." To you, "hold them accountable!" is a word game intended to confuse listeners into inaction, and to conveniently disguise your true motives.
The real way to hold them accountable is to start voting against all of them, voting for the dissent parties until such a time as those parties become the statist ones.
