I've been following this project for a while, and I applaud what you're all trying to accomplish

As much as it would make it REALLY easy for me were you to choose DE, I decided to register on the forum because I think there's something you all really need to know about DE.
Strictly IMHO, hell will freeze over before people in DE go along with the FSP. I live in Delaware County, PA and work as a consultant in DE. The state line is a whole three miles away, and I buy everything I can there. I'm somewhat familiar with northern DE.
Delaware is really two different states. North of the C&D, it's really crowded, and VERY leftist (If you don't believe me, go buy a street map showing northern New Castle County and southern Delaware County (it's in PA). The population density difference is striking).
Here's the scoop, from what I can see: it's true that there is NO sales tax, and very low property taxes (roughly 33% to 40% of those in PA and far less than half of those in NJ). This is also a problem, though: because of the low PROPERTY taxes and the huge number of low-paying retail jobs, it attracts a whole lot of people from PA and NJ who are of little means (i.e., they move there and take those retail jobs). Far more often than not, these people are die-hard Democratic voters. The income tax is progressive, and at the high scale, it hits pretty hard: every dollar you make over $60,000 is taxed at 5.95%. While there is no sales tax (as opposed to a 6% sales tax in PA), it means that, if you like to save your money instead of spend it all, it really hurts since you get hit with the tax before you can invest it or gain interest. By contrast, the income tax in PA is a flat 2.8%, so people with higher incomes (and likewise, the skills that earn them those incomes) tend to live in PA. This is one reason why neighboring counties in PA tend to be more conservative than New Castle County (DE).
Wilmington. Hmmm, how do I describe it in a flattering way? Well, it isn't Chester

(I went to high school in Chester, PA, so if anyone on this forum lives there and is offended, well, what can I say...it's TRUE) .Wilmington is, however, a Democratic stronghold. I'm sorry, but I really think that nut is uncrackable. A hundred years from now the inner city neighborhoods will be just as Democratic as they are today, if not more so.
