Republican Capitol Hill aides believe they will retain their congressional majorities in next week’s elections, even as they expect their party’s presidential candidate, Donald Trump, to lose, according to CQ Roll Call’s latest Capitol Insiders Survey.

Fifty-one percent of the Republican aides who took the poll say their side will hold 51 or more Senate seats come January, while another 21 percent predict a 50-50 split. And only one Republican aide who responded expects the Democrats to win the House.

The survey was emailed on Oct. 24 and filled out by 212 aides, of whom 98 are Republicans, 110 are Democrats and four are independents.

Staff members had until Oct. 31 to respond. So some were able to factor in FBI Director James B. Comey’s announcement that his agency was reviewing new emails potentially relevant to the bureau’s previously closed investigation of the private email server that Democratic presidential candidate Hillary Clinton used while she was secretary of State.

Other aides had responded prior to Comey’s announcement last Friday. So even before that bombshell gave Trump new hope, the GOP aides were staying cool.
