I'm glad to see the Dems getting some notion of what they need to do. They still seriously lack any clue about framing themselves as leaders.
If I understand the slogan, they are open to the possibility of improving things once we get everyone working together. Like that's going to happen. So maybe America can do better. But not with watery politicians spouting focus-grouped slogans.
A theme with kick (not the best possible I'm sure, but for illustration): "Let's Get America Back." There's a theme you can riff on. Get the rule of law back. Get our guns back home from around the world. Get back our lead in education, scientific research, industry, freedoms, privacy, free assembly...
And this says the Democrats are personally inviting you to participate in improving the nation. If they get a slim majority or a mandate, doesn't matter. They'll still work hard for, and with, ordinary people. It echos the calls Roosevelt and JFK made for people to get active in doing good.
Maybe my suggested theme is no good, but their's is just achingly dull and weak. And there should be a contest or something to get decent slogans for the Democrats.
Much more important, of course, is that the Dems come up with a specific (and easily stated) plan for making things happened, a plan based not on opinion polls, nor what Republicans might say about them, nor their career interests, but from what the country really needs. This would be worth a whole galaxy of spin.
[This poll is, well, I just can't resist thinking up absurd polling questions.]
