For a decade, No Labels has weakened the moderates’ position by building their own networks of donors and political leaders that could otherwise have strengthened moderate factions (and they did in the 1980s and 1990s for Democrats). Now, No Labels is not just luring away moderate donors or politicians—they are coming for the moderate voter, too. The cost is now clear. We need to build up the moderate wing of the Democratic party. Both demographics and recent history show that it is the main vehicle for building centrist power.
