He's not slamming Obama. He's referencing the obstructionist republicans in the house and senate who have done nothing over the past 7 years. I will say this, he is overestimating Hillary abilities if he thinks she can get them off their asses and actually govern like they were elected to do. I'm not sure the reanimated corpse of Ronald Reagan could perform that feat of magic.
