shortcut:I'm not seeing the problem? Is it because its a woman, or has she done something that's so much different that the other politicians?
Her attitudes about fiscal responsibility seem to be informed by her experience as governor of Alaska, where money miraculously flows into the treasury from oil revenues and federal largesse, where low taxes and high government spending are entirely compatible. You can debate the appropriate level of taxation, but she seems to think that the country would work best without any taxes, without having a good idea of where to cut spending or how else to raise revenue.
Her attitudes about science, from environmental challenges to basic biology to basic math about oil production and consumption, are indifferent at best. By choosing someone with such disregard for the best facts available as the president-in-waiting, John McCain has shown a reckless disregard for, well, all future decisions that might be made in the Oval Office during his term.
Her lack of a record of even talking extensively about foreign policy makes her an almost completely unknown variable when it comes to war and peace and America's place in the world. Obama and Biden and McCain have been involved in foreign policy debates for years, and we know where they stand. Palin might be okay or she might be a disaster; she might have a well-developed sense of the world or she might be the product of her handlers. We just don't know.
She's for shooting puppies from airplanes. Okay, I guess her policies to support hunting over wolf conservation isn't exactly a threat to our nation's future. But it's one that I don't believe most Americans, myself included, would agree with.
It's not because she's a woman, and it's not because her political resume is even shorter than Obama's. It's because at the important level of how she would address the issues, she's somewhere between "unknown" and "bad."
