Yet as the parade veers left, the Democrats must always race out to be in front of it. This week’s Gallup poll says that a record high 47% of Democratic voters identify as both socially liberal and economically liberal or moderate. That’s up 8 points since the 2008 election of President Obama and 17 points since 2001.

Just as yesterday’s luxuries become today’s necessities, Democrats are continuously redefining what it means to be Democrats.
They celebrate their many gay-marriage victories, with a final, 50-state resolution due soon, perhaps any day now. But that won’t be the end of the issue. As recently as early 2012, even Obama opposed gay marriage. Within 15 minutes after he publicly reversed course, liberals were routinely comparing gay-marriage opponents to racists, and 30 seconds after that liberal judges started forcing evangelical bakeries out of business for declining to participate in gay weddings.

Just this spring, Obama’s own solicitor general let slip that “it is certainly going to be an issue” whether universities that decline to back gay marriage will be able to retain their tax exemptions.
