"One of the two major parties, the Republican Party, has become an insurgent outlier � ideologically extreme; contemptuous of the inherited social and economic policy regime; scornful of compromise; unpersuaded by conventional understanding of facts, evidence and science; and dismissive of the legitimacy of its political opposition,"
Couldn't have said it better; some of the kooky ideas coming from the far Right (which is sadly virtually the entire Republican Party) are truly bizarre beyond description.
