Well this affects a lot of people. You'll often hear American Democrats say the 'poor' vote against their self interest.
That's actually a remarkably arrogant statement. As if they 'know' Democratic policies benefit the poor.
In reality, it is much more complex.
1. I'm in Canada and a lot of poor people anecdotally have changed to either vote NDP (very left) or conservative. Their reasons are that the Liberals (more similar to Democrats in the US) aren't working for their interests. They work for the public sector unions and special interests groups... Some have enough hope in government and vote NDP. Other say screw it, the government will never care about the poor and just vote conservative hoping to at least keep what they can.
2. A lot of people really do wish to be left alone. It's not against their interests, if their goal is to be left alone. I grew up in Africa. One thing I can tell you is that apart from the violence, I liked the life down there. I don't know what my poverty level was, but it was probably pretty poor. The thing is, we had a roof on our head and lived pretty much okay. I suspect a lot of people in 'red states' might appreciate the independent living and simple life more than those in other states. You can live very cheaply in red states. It might not be the best life. It might not have the best healthcare. It might not bring them above certain poverty threshold numbers. But they can live in their own home and do their own thing.
I honestly couldn't picture myself poor in a 'blue state' I'm currently in a city (Toronto) in Canada. I certainly couldn't bring myself to live poorly here. Housing and property taxes up the wazoo. Fees, fees, and more fees.
If I ever lost my job or became poor, I would also seek the best way to reduce my cost of living and live a simple life. I'd move out to the boonies somewhere.
I know this is not everyone's cup of tea. But it is what it is.
3. The US is not some socialist state that helps the poor. I think Canadians are starting to see this in their own policies as well. If you look at Europe and others, you'll start to see the same thing as money gets tight. But it's especially true in the US. The Democrats aren't 'left' enough to really help the poor. Much like in Canada, they really just help the public sector unions, and a few sectors like the auto industry and healthcare... They're not out there giving poor people jobs. Sure, they speak in the name of the poor. But people have heard that before.
4. This last point, I think is more on the values level for the red-state. They know everything has a cost and things will have to be paid for. Also values play an interesting role. You mentioned the 'multi-coloured worker-bees vote left'. Well think about that from the red-state American. These 'colored' people are leaving their ghetto country and have ghetto leftist values that made their country ghetto. If we need to keep America prosperous, we need the values that made America great.
Again, I'm not saying I agree with that, but let it sink in for a second. Red-states aren't getting immigrants on mass from Finland/Germany. They're getting it from Mexico.
