Republican Sen. Ted Cruz fended off rising-star Democrat Beto O'Rourke to win re-election in a much-watched Texas race that began as a cakewalk but needed a visit from President Donald Trump to help push the incumbent over the top.
But O'Rourke visited fiercely conservative parts of the state that his party had long since given up on, while shattering fundraising records despite shunning donations from outside political groups and pollster advice.
Democratic Sen. Joe Manchin of West Virginia has turned back a challenge by Republican Patrick Morrisey to win his second full-term in a state carried by President Donald Trump.
