President Donald Trump’s crusade to end the filibuster is driving a deep wedge among Senate Republicans, with new senators opening the door to weakening it and others unwilling to take a stand on what has become a GOP political land mine.

In a series of hallway interviews this week, the Washington Examiner asked 41 of the Senate’s 53 Republicans for their view on the 60-vote threshold, which Trump has spent the last week railing against as Democrats block a bill to end the government shutdown. Responses for another half dozen or so were provided by spokespeople.
