Reporter Kate Kaye talks to Dan Backer, general counsel and treasurer of Great America PAC, one of the larger super PACs that supported President Trump in 2016. They say they have built a list of at least 3 million active supporters. Great America PAC has used atypical approaches like running 1-800 tv ads to find those low propensity unlikely voters who Trump inspired to become politically engaged. They’ve spent around $200,000 so far in February alone. One goal is to encourage people to contact their senators in support of Trump’s nominees and initiatives like repealing Obamacare and building a border wall and Backer has been running ad tests to see what works most efficiently.
