So the Obama afterglow is fading and the word "establishment" is starting to look like both major parties? No need to hyperventilate; you're not alone. There is support among like minded people.
One of those like minded people has taken the time to consolidate some advice for doing something about it. I don't agree with it all*, but you can be the decider.
Check out the recent post: "What to Do If You Are Disatisfied with Obama and Bush" at the Godless Liberal Homo blog.
* One of the "action items" is to "Stay a Registered Democrat." This can be argued both ways.
An alternative perspective is to "Register Green." In doing so, you cast a vote that will be recorded for all to see in the County Election Board tables of registered voters, including Democratic Party operatives.
As the numbers in the Green Party column grow, the Democrats will realize that they are actually to the right of a growing group of people... this will help pull the Dems back to the left. True, you give up your primary vote, so be sure to convince at least one friend who would NOT have voted in the primary to do so... now you've offset the minor benefit of remaining registered Dem and you still have your number reflected in the County Election Board's tally of registered voters for all to see. Simple.
Final Note: Is it only me, or when you first glance at the photo in the upper right, doesn't it look like "Change Label"?
