The Government Shutdown, Who's to Blame?

There are many different groups that are responsible for causing this government shutdown. I feel that while the Republicans are partially at fault, they have been blamed far too much for causing and extending the government shutdown. I don't intend to sound biased, but the facts all point one way. That is in the direction of President Obama. During the final 3 days before the shutdown, the house passed 4 separate budgets. The senate refused to discuss these budgets until mere hours before the shutdown. In the 3 days since the shutdown, the house has passed 7 more budgets getting progressively more moderate with each one. The most recent defunds Obamacare for only 3 months. The senate has voted all of these down. One might begin to think it is all the fault of the senate at this point, but the trail goes back farther. Obama has threatened to veto any budget that doesn't fully fund Obamacare. This has scared off many senators that would otherwise vote to pass the budgets because they don't want to be seen going against their party and not have anything good come out of it. It will be interesting to see if the President actually carries through when the budget finally gets passed. It is only a matter of time as the senate is having smaller and smaller majorities each time. The big question is: who will back first, the Republicans or the Democrats?
