The chart above depicts the percent of contributions in U.S. Dollars donated to Republican and Democrat candidates/parties/affiliated groups, seeking national office during the 2020 election cycle, donated by employees, or owners, of the companies listed, and those individuals' immediate family members, based on data collected from www.opensecrets.org.
In some instances the money was possibly donated by the actual company, but the bulk of it typically comes from individuals within the company, or immediate family members of individuals within the company. The only way I'm discussing the actual organization is if I reference it as "the organization itself", otherwise, I'm talking about the jargon mentioned above (individuals within the company, owners, employees, direct family, etc.). In some instances, the money considered contributed may come from PACs affiliated with the mentioned organization.
68.3% of donations from those affiliated with Xfinity (owned by Comcast) went to Democrats, for a total contributed amount of $7,777,498.
66.97% of donations from those affiliated with Lively (owned by Best Buy) went to Democrats, for a total contributed amount of $530,340.
55.09% of donations from those affiliated with T-Mobile (majority owned by Deutsch Telekom and Softbank Corp) went to Democrats, for a total contributed amount of $2,008,852.
69.93% of donations from those affiliated with Verizon went to Democrats, for a total contributed amount of $3,407,235.
