Well, you can’t be a political advocay group and have that 501(c)(4) status.
You have to be non political. Like for example, “Organizing For Action” OFA.
Organizing for Action (OFA) is a nonprofit social welfare organization and community organizing project in the United States, heavily affiliated with the Democratic Party. It is the successor of U.S. president Barack Obama’s 2012 re-election campaign and of Organizing for America, which itself succeeded Obama’s 2008 campaign.
Founded after President Obama’s re-election, the group seeks to mobilize supporters in favor of Obama’s legislative priorities. OFA is registered as a 501(c)(4)organization

As I understand it, 501c(3) groups can’t do partisan politics at all; 501c(4) groups can legally do some but politics can’t be a major part of their operations.
