Having received minimal publicity in the previous elections , thus contributing to the low voting share that the party received , the Green Party gained significant exposure and media attention in the lead-up to the 2012 Green National Convention and the 2012 presidential election , starting with media personality Roseanne Barr 's announcement of her presidential run with the Green Party . Using the publicity gained from the announcement , Barr praised the Green Party and championed their beliefs through interviews and public statements , which were often profane and harshly critical of both the Democratic and Republican parties . Barr , however , lost the nomination at the 2012 Green National Convention to physician and activist Jill Stein , who had gained the support of Green Party delegates through her " Green New Deal " platform of progressive economic policies centered on the prevention of future financial crisises and the acceleration of global warming . Stein 's campaign for the presidency focused mostly on keeping the publicity gained by the Green Party and gaining support from independents and dissenting Democratic and Republican voters , often echoing resentment towards the two parties . This included a court challenge against the Commission on Presidential Debates by Stein that sought to include her in the official presidential election debates . Stein 's campaign also gained media attention and exposure through a series of nonviolent protests , including those against the presidential debates , the Keystone XL pipeline , and foreclosures , which had Stein arrested , and even jailed , numerous times
