So, Politico believes Joe Manchin can run as a liberal democrat in 2016 and he'd not be a flip-flopper. WV is a conservative state, so you have to be a conservative Governor. Buuut you can have a liberal plan for the entire USA at the same time. I'm sure democrats would love that.
I'm sure there are many people who support death penalty in conservative states and are against it in liberal ones. Obama should make same-sex marriage legal only in blue states. That's the solution. 2 Americas. Or 3. Or 4.
It is not unreasonable for a governor of a state to believe that what their state wants, or what their state can afford, is not necessarily the same for the 49 other states. Some people believe in the autonomy of the states whereas others believe in mandating state behavior out of Washington. Romney believes in the former, and Obama believes in the latter. Obama believes that Washington is the solution whereas Romney believes that Washington is the problem.
This is not complicated.
You think states should do the governing wall-to-wall. That's a perfectly valid opinion. But we are not a nation of "Blue States and Red States". We are the United States. There are times when we're fifty states and there are times when we're one country, and have national needs.
