Why do conservatives keep calling Obama a socialist?

His actions are totally in keeping within the socialist ideology. He is bleeding us dry financially as a nation, using our wars and quasi-wars, allowing illegal immigrants to devastate our tax revenue, and siding with unions that are bankrupting state and local communities. Meanwhile, he had the government take control of two automakers, several banks (including the entire college loan industry) and put in place mechanisms to gain control of the health insurance industry. Sure, there are many other countries with leaders that lean farther left, but they are in countries where the left has been in control and implemented these programs already, so they are pushing the window farther to the left. Here in America, Obama knows he can't go as far as he wants, so he does as much as he can without totally destroying his chance at reelection. God help us if he gets reelected, because then he's gonna push even harder toward his agenda.
