WASHINGTON — Republican Sens. Marco Rubio of Florida and John McCain of Arizona turned toward the general election Wednesday with GOP control of the Senate at risk, each facing lesser-known Democratic House members who’ve sought to link them to Donald Trump.
Rubio and McCain have two tough months of campaigning ahead, but on Tuesday they easily dispatched their Republican primary opponents, outcomes that underscored the party establishment’s dominance of House and Senate primaries despite the nation’s turbulent anti-establishment mood and Trump’s outsider candidacy.
Not a single senator of either party has lost a primary this year, and in House races only five incumbents have lost, in several cases because they were under indictment.
Rubio and McCain are supporting Trump for president, albeit with obvious reluctance after they were the target of his insults and Rubio ran against Trump for the White House. Unlike other incumbents, Rubio and McCain are extremely well-known with their own brands distinct from Trump’s, but the mogul’s impact on their candidacies remains unpredictable in states with large numbers of Hispanics, many of whom Trump has alienated with his insulting comments about Mexicans and his hard line on immigration.
