Senate Majority Leader Mitch McConnell, with a rare smile and spring in his step, made clear Wednesday that he is happy with the outcome of the election that has increased his majority by at least three senators, calling President Donald Trump's efforts "very helpful" with that victory.
Several major races are still pending. Even in the Senate where Democrats lost ground, they won the popular vote in those races by 15 points (they got 57 percent of the popular vote; the Republicans - just 42 percent).
In suburban areas where key House races will be decided, voters skewed significantly toward Democrats by a almost 10-point margin. Reps. Jeff Denham (R-CA) and Mimi Walters (R-CA) now hold small leads, as does Republican Young Kim in an open Orange County seat, while Rep. Dana Rohrabacher (R-CA) trails by a bit. The Senate was always an uphill battle for Democrats, who needed to defend 26 of the 35 seats in play, compared to just 9 for the Republicans.

"But it may seem that way because we are coming off a two-year drought of no subpoenas", said Representative Gerald Connolly of Virginia, the top Democrat on the Oversight subcommittee on government operations. Overall, 43 percent of voters said they were very concerned about women not being believed when they make allegations of sexual misconduct, and another 35 percent were somewhat concerned.
Welch said the House has responsibility to do both in the next two years, but he would like to see the emphasis on passing legislation with bipartisan support to build up the public's trust in Congress.
Democrats say that when it comes to the administration's response, for example, to the "caravan" of Central American immigrants, they want answers about the rationale behind the troop deployments and details on the force's rules of engagement.
Smith and more than 100 other current House Democrats have already sent a letter to Defense Secretary James Mattis seeking a response.
"I don't think we can discount the impact of suburban voters", he said.
He said that holds true for the spending bills Congress must still negotiate by early December. "If all we're doing is investigations, blame and vengeance, then we will never have a chance to really get that legislative credibility that's essential", Welch said.
He said he was waiting on the Florida results and possible recount, and said Arizona is "not close to over" with perhaps 600,000 ballots still outstanding.
"If it's not the Mueller report, the focus will be redistricting or campaign finance reform", he said.
