Rep. Beto O’Rourke’s (D-Texas) campaign announced a $1.27 million media buy on Monday, using the money donated to his campaign after Cruz had launched attack ads against the three-term Congressman earlier this month.

The release noted that the TV ads would be “positive,” and would run in each of the state’s 20 media markets.

"Texans in all 254 counties of our state are proving that together, we will be the big, bold, confident answer to the small, petty, negative attacks that are coming our way," O’Rourke said in a release.

O’Rourke has pledged to refuse corporate PAC money in his campaign, and said in the release that the $1.27 million came from 39,000 contributions of an average of $32. The total raised exceeded the campaign's $1 million goal.

The Democrat has been one of the top fundraisers in this election cycle.

Recent polls have found O’Rourke within striking distance of Cruz, though the incumbent senator remains the favorite.

The Cook Political Report recently shifted Cruz’s seat from “likely Republican” to “lean Republican.” Cruz last week asked Trump to come campaign for him in Texas.
