In one case he is right. As we saw GWB take the unity that we had after 9/11 and destroy it with partisan politics and hate our nation was weakened. I just wonder, since it has been completely republicans destroying the unity of america since 2004 and right through 2008 and the present what the **** he is whining about? It was the republicans who held america hostage last summer with their partisan politics trying to destroy the US to prevent another Obama presidency. It is republicans who are uncompromising and consider compromise to be a dirty word. It is republicans who have made hatred and fear their tactic. That entire clip is much more focussed on republicans in the US than the dems who have compromised, and obama who has reached out across the aisle repeatedly only to get his hand bitten by the ravenous hatred of the right wing.
To tell us that he is supposedly the candidate of unity is just another of mittens lies and deceptions. He has run a campaign so dirty he even divided his own party in the primaries. I know the republicans here will defend this as they have no concept of truth, or even their own divisive behavior.
All I can say is that they can feel glad lies and dishonesty have no punishment because they would all be hung for their bullshit.
