I heard this argument a lot, and perhaps the people I find myself around are abnormal, but I'm trying and failing to come up with people I know who vote along party lines simply because it's one party or the other. Just about everyone has at least one major issue that keeps them from voting the other way, and most have multiple reasons. I guess I have seen something like it, now that I'm thinking about it -- but it's generally a negative condition, i.e. "I'm not voting for X simply because they are part of party Y." They're not necessarily voting for their party because it's their party, but they're doing it because it's not another party, or more specifically, not a particular candidate.
