It seems increasingly apparent to me that one of the Democratic Party's biggest enemies is not necessarily the Republican Party, but, rather, dangerous assumptions by Democrats themselves.
There are several of these assumptions that have, increasingly, been bothering me over the past few years. It started way back in 2008 when, fresh on the heels of a Democratic wave election year, some progressives, including a fair number of people on this site, started prematurely declaring the Democratic Party as the "permanent majority party."
It rubbed me the wrong way that, after one election, people could be so quick to start declaring the war over based on one successful electoral battle. But the lack of critical thinking, logic and reason that such assumptions entailed bothered me even more.
