Mainstream politicians have sometimes sought to co-operate or build alliances with populists. In the United States, for example, various Republican Party figures aligned themselves with the Tea Party movement, while in countries such as Finland and Austria populist parties have taken part in governing coalitions. In other instances, mainstream politicians have adopted elements of a populist political style while competing against populist opponents. Various mainstream centrist figures, such as Hillary Clinton and Tony Blair, have argued that governments needed to restrict migration to hinder the appeal of right-wing populists utilising anti-immigrant sentiment in elections.
