Originally posted by mikemike I wouldn't really say it is a conclusion, more of a hypothesis I guess. I don't think anyone has done any real research tracking party switching or leaning patterns over time. It just seems that the democrats put a lot of effort into hustling to get first time voters registered (and has been doing that for decades) while comparatively struggling with repeat voters. I can't say definitively whether those people then switch to republicans or just get apathetic and check out of the voting scene altogether but it seems like the republicans maintain parity without putting the least bit effort into recruiting new voters.
A quick google and seems like the research that comes to the top has to do with the elected official's switching parties, and not the voting public's.
The traditional view of Republicanism (well, in the last century anyway) is that as people become property owners and older they tend towards Republicanism, in the interests of their property and its related expenses. Property tends to be a long term proposition - and that's a basic definition of conservative, no?
As I first said, the Dems have a constantly growing market, so a get-them-in-the-door works. Some will stay and buy more, others will return occasionally, and some won't at all.
One explanation of the growth of the Independents has to do with the polarization of social vs economic policies in the two parties. I've met several people who mumble 'oh I vote for whoever is the best candidate' when asked... these might have been Rockefeller Republicans in the past, but now in in a Blue State, there is shame about the more extreme Republican social politics and even some of the economics. I could imagine something similar is going on in Red States, in reverse: people who would have been conservative Democrats are now Independents and mumbling 'oh I vote for whoever is the best candidate' when asked by their (likely) conservative Republican friends.
