I was thinking about this part of your answer. Why doesn't the LP go after Dem constituents? There are many blacks who won't even consider voting for the GOP due to a largely irrational bias, but may consider voting for a third-party with free market values mixed with suspicion of government. If blacks would start voting for the LP it would be good for the LP and good for the country. It might even cause the Dems to shift a tad in the free-market, school accountability direction.
That's a very good point you bring up and some people within the party (especially Jacob Hornberger, US Senate candidate in Virginia) have proposed doing just that in their campaigns. I'm concerned that many blacks will still have a problem with the LP however for the same reason they have one with the GOP- the affirmative action issue. As you probably know we're also opposed to quotas, preferences etc. and this is one of the key issues that keeps a lot of blacks (or so it seems) on the Democrat plantation. In fact the LP is more consistent in opposing quotas than many within the GOP, so this may get in the way of some of our efforts. Nevertheless I'm confident that we can make inroads by appealing to the historical and justified mistrust many blacks have towards the federal government.
