Well I think I have discovered maybe WHY San Fran. needs to invite the Ilegal's or rather needs them.
It could be due to the fact that they are and have been losing population when most US cities are growing over the last several years.
In July 2000 San Sincisco had a population of 776,733 and in July of 2006 it dropped to 744,041. That's a loss of 32,692 people in 6 years and this is when they have been adding Ilegals by the droves. Fasinating isn't it???
If you go and look at the cities that are losing population, such as San Sincisco and Detroit you will find that the ones losing population the most are completly run by Democrats. You know the numbers show so clearly the facts. Ha Ha...
