How much exactly?
My own cynical belief is that any group who gets power will ultimately be corrupted. That's why I have more interest in advancing specific issues such as abortion restrictions, school choice and term limits rather than a particular party.
I respect your committment to issue-orientated activism; in fact I share it. However I don't think it's enough by itself. One of the political parties is going to hold power in this country; the realist in me accepts this which is why I work to promote the LP as a viable political alternative.
I'd have to go back and check tax returns. There was a cut.
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.
