CNN recently sat in on one of Sen. Elizabeth Warren’s “call time” sessions with small-dollar supporters, just days after she declared that she would not participate in any fundraisers, dinners, receptions or phone calls with wealthy donors during the primaries.

“Warren’s advisers say their strategy is about building a solid foundation for the long-haul. The time saved by skipping glitzy fundraisers and call times with deep-pocketed donors is being invested in more organizing events and town halls, they say. Warren has traveled to eight states — Iowa, New Hampshire, South Carolina, Georgia, Nevada, California, New York and Texas — as well as Puerto Rico so far this year.”

“There is time set aside every week for phone calls and meetings with grassroots supporters and small-dollar supporters, according to advisers, who say Warren has made hundreds of grassroots calls so far this year.”
