The real problem is they have too many people to appreciate.
Republicans can preach one message and everyone gets on that message cause everyone knows who their base is (white men and women)and what they want. So the Republicans get that support even tho they don't actually do anything but, the message is always strong and loud and it looks amazing cause they dictate the what the narrative is no matter if its something good or bad.
Dems can't cause they have to appease whites, blacks, others, moderates, liberals, poor, middle class, rich, the gays, the other gays. Too much for them to try to appease. So they pick and choose when to play it safe and when to go do something and usually bungle that too. They struggle with a message cause not everyone is on the same page.
Its a reason they can't have the backbone and not look like the bad guy and piss people off. Dems would rather starve while watching the other side roll in the mud and catch a frog to eat. They refuse to get in the mud and get dinner too.
One band. One sound.
