NYT:

The billionaire environmentalist Thomas F. Steyer and his political advocacy group, NextGen Climate, will spend at least $25 million on a get-out-the-vote campaign targeting young voters this year in seven mostly battleground states, the group announced on Monday.

Mr. Steyer, the single biggest political donor of the 2014 midterm election cycle, said the campaign would target at least 203 college and university campuses. He called it the largest youth voter outreach program ever undertaken by a candidate or political campaign.
