Former New Jersey Governor Chris Christie laid out his game plan for defeating former President Donald Trump in the Republican presidential primary. Christie, who lost to Trump in the 2016 GOP primary before endorsing him, spoke at St. Anselm’s College in New Hampshire on Monday. So far, he has drawn Nikki Haley – his former ambassador to the United Nations – as an opponent. It is widely believed several other Republicans will challenge the former president, including Christie, perhaps. The 2016 New Hampshire primary was won by Sen. Ted Cruz (R-TX), who was Trump’s last opponent standing before he suspended his campaign.
