Stand Up Republic Foundation (formerly Stand Up Ideas) is a right-leaning advocacy organization created by failed presidential candidate and vice presidential candidate Evan McMullin and Mindy Finn, respectively. The group is affiliated with Stand Up Republic (SUR), an advocacy nonprofit critical of Trump administration policies.
Stand Up Republic Foundation and the left-wing litigation group Protect Democracy Project co-published The Republic at Risk, a joint report that criticizes the Trump administration as anti-democratic and dictatorial. 
Stand Up Republic Foundation originated as Stand Up Ideas (SUI). As of June 2019, the group has been renamed Stand Up Republic Foundation, likely to match its 501(c)(4) lobbying arm, Stand Up Republic (SUR). The website www.StandUpIdeas.com redirects to Stand Up Republic Foundation’s website.
“The Republic At Risk”
The Republic At Risk is a 2018 conspiracy theory report co-published by SUI and the Protect Democracy Project (PDP), a left-wing organization critical of the Trump administration. The report claims that, while “millions of federal civil servants pledge their loyalty . . . to the American public and Constitution,” President Donald Trump “has shown little respect for these traditions.” It further accuses the President of “quashing dissent”; “delegitimizing communities” of minorities by “appeal[ing] to divisive and hateful strains in our society”; and “corrupting elections” in part by “refusing to condemn Russian interference in the 2016 election.” The Republic At Risk also accused President Trump of “corrupt efforts to operate government institutions for the benefit of himself, his family, his friends, and allies.” 
The report claimed “President Trump has exhibited the habits and actions of a budding authoritarian in each area of potential democratic decline in just his first twelve months.” According to the report, “we are under immediate threat from Mr. Trump’s authoritarian tendencies”: 
While many have followed his [Trump’s] presidency as a seemingly unending series of unrelated scandals, a more coherent narrative shows that all of his unorthodox actions are part of a singular story of a president with disturbingly autocratic tendencies presiding over a democracy at risk.
The Republic At Risk recommended “larger reforms to rebuild public confidence in democratic government,” including the potential abolition of the U.S. Senate or Electoral College and fundamental changes to American elections: 
- “Reduce the negative impact of money in politics” supposedly brought on following the 2010 Supreme Court decision in Citizens United v. FEC;
- “Ensure congressional districts are representative by ending gerrymandering practices”;
- Reduce “economic inequality”;
- “Review alternative electoral formats for electing legislators”;
- and “review how our democratic structures should work in a time of division of social change.”
