You know something is up when you look at the "conversions" on this issue. There are lots of people who were formerly pro-abortion that are now strong pro-life advocates. Nobody changes their mind the other way except limp-wristed Republicans who decide that a pro-life stand is a political liability.
I met a guy a few years ago who is now a Republican Congressman. Married to a former National Right to Life spokeswoman and everything else. If this guy represents the future of the pro-life movement in Congress, then we are doomed.
I don't expect to ever see abortion as a main campaign issue. Just because it would not impact that many votes. The pro-life and pro-death sides are already committed. And the sad truth is that the majority of voters don't care about anything that does not effect them personally. That's why I give to Right-to-Life groups, it's their job to try to reach that apathic middle.
If you want to see campaigns that make abortion a major issue. Then work to remove these limits on campaign contributions. Alan Keyes has pointed out that these limits force candidates to water down their message in order to attract support from as many people as possible. Also no limits would allow candidates to base their campaign on just one or two issues. Imagine what would happen if a few rich pro-lifers each gave Alan Keyes a couple of million, to get his message out. At the very least we would be having some very interesting elections.
If you don't like the way campaigns are being run, then go out and help run one. Congressional campaigns, even for incumbents, are run nearly entirely by unpaid volunteers. Or is it easier to sit home and bitch.
