In North Carolina, Democrat Roy Cooper faces a challenging Senate race in a state that leans Republican for Senate seats, despite its willingness to elect Democratic governors. These races underscore the prominence of experienced political figures and the evolving dynamics of voter preferences. Toronto Star+2
