I believe I have seen people here mention this idea before.

Adopting a tactic their party bashed as a stunt in the watershed 1994 elections, House Democrats plan to unveil their election-year themes by rolling out a “Contract with America”-style legislative blueprint in September.
Led by Minority Leader Nancy Pelosi (D-Calif.), Democrats are in the conceptual stages of putting together their version of the “contract,” crafted a decade ago by then-Rep. Newt Gingrich (R-Ga.). The GOP’s plan laid out a series of promised changes they pledged to enact if elected to the majority and was the centerpiece of a campaign in which Republicans rode a wave of voter discontent to their first House majority in 40 years.
Democratic sources say in their version leaders will unveil a “palm card” with a handful of themes designed to define the party and explain why it would provide a better alternative to the current majority. Unlike the original contract, which laid out specifics such as support for Congressional term limits and applying workplace laws to Congress, this version is expected to shy away from detailing policies.
“It will be a clear message about where Democrats want to go, what we stand for and what we will do when we take back the House,” one Democratic leadership aide explained. “It will be broad enough so that all Democrats can get behind it, but it will also show our differences from Republicans.”
