Democrats have cohesion. Everybody's on the same page, they back up each others lies, stay on whatever message they're told and pound that message home every chance they get. They stay together, on topic, ad nauseum and that's why Barry is back in the White House.
Republicans eat their young.
The republican party is a bone yard of rich, extraneous old men who only care about their next election and are worried and fearful of new blood.
These old farts could learn a lot from the dems. GET BACK TO THE PARTY ROOTS, STAY ON MESSAGE, POUND IT HOME AND STICK TOGETHER.
