From Wisconsin conservative James Wigderson:
Wisconsin Senator Tammy Baldwin (D) received bad news last week when her net approval rating placed her in the bottom ten of U.S. Senators, according to Morning Consult last week.
“Sens. Tammy Baldwin of Wisconsin and Claire McCaskill of Missouri, who are both seeking re-election, remain the least popular Democrats in states carried by Trump, with voters split down the middle over their job performance,” according to Morning Consult.
McCaskill is frequently listed as the number one target for Republicans heading into the 2018 election cycle.
