Missing Mobile Numbers

Texting is revolutionizing Democratic campaigns. However, most campaigns do not have mobile numbers to text. So, many turn to mobile acquisition to attain mobile supporters. While mobile acquisition is an excellent way to gain new supporters, campaigns often do not realize the untapped value in their existing lists. Therefore,
