The Serve America Movement (SAM) was a big tent political organization founded in 2017 by Morgan Stanley lawyer Eric Grossman.

[3] The party has received most of its financial support from Charles Wall, a former vice chairman of Philip Morris International, who provided more than 93% of the group's funding in 2020.

[9][8] The party generally took a big tent approach, as it was founded by former George W. Bush administration staff members.

As a result of the ideological foundations of the party, it aimed to attract both moderate Republicans, Independents, and centrist Democrats[20] in a movement to work for numerous electoral reforms like Ranked Choice Voting, and Open primaries.

The party followed a set of general principles rather than an objective ideology of policies, in order to pursue a common outcome without divisive political differences.
