Sen. Elizabeth Warren Elizabeth WarrenNo new taxes for the ultra rich — fix bad tax policy instead Democrats back away from quick reversal of Trump tax cuts It's time for newspapers to stop endorsing presidential candidates MORE’s (D-Mass.) presidential campaign said on Sunday that it brought in more than $29.3 million in February, marking its best month of fundraising to date.

Warren's donations last month averaged $31, campaign manager Roger Lau said in a memo.

Warren saw a surge in donations after her strong performance in the Nevada debate, with her campaign raising $2.8 million in one day. It also raised more than $9.5 million in the period between Wednesday and Friday of that week.

With the influx of donations, the campaign is now increasing its spending in Super Tuesday states to more than $2.4 million on TV, digital and traditional media advertising, Lau said.

“We’ve already reserved media across key markets in Arizona, Illinois, and Georgia — and into Wisconsin, which finishes voting in April. We’re in this race for the long haul,” he said.

Despite Warren’s fundraising haul, she has yet to win a contest in the first four voting states.
