I am really not sure how this has a whole lot to do with Obama, however. What it really demonstrated was that the Republicans have a really great plan of doing nothing which has come to full fruit with the Republican Senate.
It had to do with your opinion that democratic elections are won from the middle. As you put it:
‘Basically, the middle has always been a better place to be. This makes sense, particularly when running as a democrat as much of the middle votes there too.’
Kerry, Gore and Clinton ran as center right candidates and lost. Obama ran a progressive left sounding campaign, got out the Yutes in 2008 and won handsomely.
Your confusing your opinions with observable reality.
