David McCormick and Mehmet Oz gave millions of dollars to their own campaigns and have the support of super PACs that separately raised millions more. Jeff Bartos and Carla Sands are also helping fund their own campaigns, while Kathy Barnette has relied on donors and has raised far less money.
Here, super PACs are listed under the candidates they support, but the groups are independent and legally barred from coordinating with candidates or campaigns.
