Sometimes local Dem organizations can be difficult and unpleasant, but I've found from personal experience that they really like newbies who pitch in and actually do the work.
http://www.opednews.com/articles/Democrats-and-Progressives-by-Don-Smith-101202-740.htmlThere are some obvious reasons why the Right wins. They generally have more money. They own Fox News and most of AM radio. They're better at marketing. Their party discipline is better. They're brazen. And for Republican party activists it's generally in own their immediate self-interest to support conservative policies.
Here's another, less obvious reason why the Right wins.
Angry conservatives take over the GOP.
Angry progressives vote third party or join an advocacy group.
In the conservative movement, disaffected groups, such as religious conservatives and Tea Partiers, mobilize their anger and take over the GOP (with substantial help from rich benefactors such as the Koch brothers).
On the Left, disaffected progressives often give up on the "hopelessly compromised" Democratic Party and vote for a third-party candidate, such as Nader, or join an advocacy group like MoveOn, Sierra Club, NARAL, PDA, DFA, or hundreds of similar groups.
I have progressive friends further to the left of me who often say things like, "Oh, you can't trust the Democrats. They'll always betray you. They'll use progressive rhetoric to get your votes, but in the end they'll escalate the wars and vote for Wall Street, Big Insurance, and the other corporate interests."
Another, prosaic reason why progressives give up on the Democratic Party is that taking over a party organization is difficult and unpleasant. Blue Doggish Democrats fight back. Party meetings are long and boring. It's so much more fun to start your own party or lead your own advocacy group! But that's not very smart. There are already too many lefty groups.
So, too often progressives flee the Democratic Party, causing it to become more "centrist" and robbing progressives of effective power. Progressives don't seem to appreciate the fact that in our non-parliamentary form of government, third parties have little constructive power. They also don't seem to realize the importance of local Democratic Party organizations.
Partly the fault lies with the Democratic Party, which hasn't defended a populist, progressive agenda and hasn't welcomed progressives into the fold. There is mutual anger and distrust between centrists such as President Obama and progressives, who have been feeling very unloved and unheard. Progressives (e.g., single-payer advocates) have been unwelcome at the table in many Democratic organizations. Obama sometimes seems to go out of his way to alienate progressives, who are nearly in open rebellion.
I see this mutual hostility locally too, in legislative district and county organizations. In party committees, the upstart progressives often leave in exasperation due to the opposition. This harms both them and the Democratic Party. Many progressives attend meetings of advocacy groups but shun the local Democratic Party meetings.
