Democratic congressional aides have never felt more confident about their party’s chances in this year’s election than they do right now.

That’s the takeaway from CQ Roll Call’s June Capitol Insiders Survey.

Democrats have felt good for a while, of course, about Democrat Hillary Clinton’s chances of beating Republican Donald Trump in the presidential election, as well as their prospects for retaking the Senate majority, since Republicans are defending many more seats and several in traditionally Democratic states.

But Democrats are now thinking seriously about the House majority, a goal that once seemed impossible. Four in five Democratic aides who responded to the June survey said they thought Democrats would make significant gains there.

“They know it’s a heavy lift and a long shot, but that there is a shot at all is news,” says Brendan Daly, whose former boss, Nancy Pelosi of California, could return as House speaker if Democrats win 30 seats in November.
