Vice President Kamala Harris and former President Donald Trump face a tight contest in November. But as they fight to gain support of battleground states across the country, Democrats are seemingly ahead in three key races as they try to continue their control of the Senate.
A new CBS News poll shows Democrats with a lead in Senate races in Michigan, Pennsylvania and Wisconsin. The poll was conducted between Sept. 3-6 and answers were based on a sample of over 1,000 registered voters in those three states. The margins of errors are plus or minus 3.7% in Michigan, 3.5% in Pennsylvania and 4% in Wisconsin.
