I don't know whether Democrats can find equally compelling areas of common ground with evangelical groups today. Perhaps Democrats can make common cause with evangelical groups over economic justice, peace, or other issues of mutual concern. The alliance between the religious right and the corporate right may seem inevitable in retrospect, but it too is built on a sometimes uneasy compromise. Proponents of religious alternative outreach are urging Democrats to cultivate compromise in the other direction (economic interests over cultural interests). Whether such outreach is feasible remains an empirical question.While Lindsay seems to harbor at least some hope of someday getting more evangelical votes, I do not, and to be honest, I don't want them. The evangelicals who don't already vote Democrat (and there are some; my parents make at least two) aren't the sort who are swayed by economic policies. The ones who are concerned with economic policy are likely to harbor a conservative, hyper-individualist, free market view of economic issues, and any talk of something like universal healthcare or government-funded arts or environmental programs will turn them off immediately. If we talked about gun-control, prison reform, or progressive taxation, we might cause these evangelicals to have an aneurysm. Then there are those who don't vote Democrat for moral and religious reasons. These are the people who vote based on issues like abortion, same-sex marriage, sex education, evolution, and the like. There simply is no reaching these two classes of evangelicals without compromising our core values, and as Lindsay herself says, "Compromise outreach to is morally unacceptable and politically naive."
Instead of focusing on evangelicals, Democrats should be focusing on the people who do sometimes vote Democratic. Some of these voters may be evangelicals, and they may even hold some of the views that the untouchable evangelicals hold, but they don't vote on these issues alone. The way to get to them is to make it clear that Democrats will do more for them, in the short-term and the long-term, than Republicans will. People like me seem to think this is obvious, but the swing voters, evangelical or not, don't see it. So, it's not as obvious as we think, and we liberals got to do a better job of expressing ourselves and getting the message out there.
My one true hope, and I think this is a genuine possibility, is that the Democratic party will become more liberal, not less so, by recognizing that the conservative moral and economic voters are out of their reach, and focusing on what differentiates us from them. When survey after survey shows that a substantial majority of Americans support universal health care, why do we de-emphasize this issue in elections? Because we think we will lose the ultra-conservative voters? We've already lost them. The more we talk about trying to win them, the further we get from what we should be talking about.
