Under the banner of “Trump 2-29,” several tea party leaders are mobilizing on social media to encourage Republicans to take Democratic ballots in the state’s Feb. 29 open primary and vote for Vermont Sen. Bernie Sanders, the most radical of the candidates vying for the Democratic presidential nomination. At the same time, Operation Chaos 2020, an initiative of the Conservative Defense Fund of Greenville, South Carolina, is conducting an online poll to select “the craziest liberal looney” for Republicans to support. (As of Thursday, that poll had Sanders far ahead of the rest of the field.)
