Obama's Economics

Thomas Sowell has a nice piece criticizing Obama's economic thinking as typically liberal. He mentions the following issues: support for unions, higher teacher pay, making college "affordable," and "alternative fuels." It's a useful critique. On the other hand, these are issues where even most Republicans take a farely liberal view in practice. There are very few doctrinaire free market conservatives in politics. So, I'm not sure Obama's support for these positions necessarily makes him unacceptable to me. The question is going to be exactly how liberal he is on each issue.
