It's been a month of ups and downs for Senate Democrats looking to defend their slim majority in 2022. The Virginia and New Jersey elections showed massive cracks in states President Biden had carried by double digits just a year earlier, offering concrete proof that the political environment is increasingly perilous as the midterms approach.
