Senate and House results have turned out to be disappointing. Irrespective of the results though, I think there were some outstanding Dem candidates who, hopefully, will continue along their paths to be the (younger!) new faces in the party.
From Washington Post:
As the presidential race headed toward a photo finish, House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Charles E. Schumer (D-N.Y.) faced a political letdown that, so far, resembled their failure in 2016 when Trump was elected.

In the highly anticipated ÂSenate matchups, Republicans scored easier-than-expected victories in Iowa, Kansas, Texas, Maine, Montana and South Carolina while establishing narrow but steady leads in Georgia and North Carolina.

Democrats’ slim chance at claiming the majority appears to rest on Joe Biden clinching the presidential race and Sen. David Perdue (R-Ga.) falling below his state’s legally required 50 percent threshold, which would set up two runoff elections on Jan. 5 in Georgia that, if Democrats won both, would deadlock the Senate at 50-50.

In that scenario, once Sen. Kamala D. Harris (D) was sworn in as vice president, she would provide the Senate’s tie-breaking vote, handing the chamber to Schumer.
House Democrats struggled to come to grips with how they managed to lose seats after Pelosi and party strategists predicted gains of 10 or more that would give them commanding control over the chamber.
Instead, they appear to be headed to the smallest House majority in 18 years.
