President vs. Congress

Why do people constantly blame the president (whoever he/she might be) for everything that happens? why is Bush being blamed for the "economic downturn" just because he's in office? Why do people ignore the fact that the Democrats (socialists) are "in control" in Congress (and have been for almost two years at this writing), where such things get done? Yes, the president has to "approve" their efforts. But there are many reasons why the president might find it necessary to sign such bills into law after they're presented to him whether or not he likes it. But Congress has PRIMARY responsibility for such things. Frankly, the possibility of Democrats (socialists) gaining control of the EXECUTIVE while increasing their control in Congress scares the hell out of me and makes me glad I'm an old man and won't have to live through much of what they create in the future. Unfortunately, my children and grandchildren WILL. (Just common sense)
