YouTube is allowing politicians to purchase precious ad space on the platform, including ads that target voters in important early voting states like Ohio and South Carolina.

The company is giving politicians and their campaign teams access to a new tool that recently launched, letting them secure advertising placements of their choice months in advance, according to The Wall Street Journal. Beginning on November 15th, Google will let buyers purchase placement on YouTube for all of 2020, the Journal reports.

The Verge confirmed with YouTube that the tool, called Instant Reserve, is a new reservation tool in Google Ads. The company is testing with advertisers across multiple industries. The goal is to allow marketers to plan and book campaigns with a fixed budget and forecasted reach in advance of the campaign launching.

Google, which owns YouTube, has seen top politicians, including President Donald Trump and many of the forefront runners competing for the Democratic nomination, spend approximately $21.8 million in advertising on its platforms. Having access to top advertising spots on YouTube, especially on the homepage, can be a major advantage for politicians.
