From Pew:

About a third of U.S. adults say television is the most common way they get political and election news (35%), while roughly one-in-five each most commonly get it from news websites or apps (21%) or social media (20%).

 

Smaller shares turn primarily to search engines like Google (8%) or to radio or podcasts (5% each). And just 3% of U.S. adults say print newspapers or magazines are their most common way of getting election news.
