Losing 41 seats and control of the House is hardly a President losing a few seats. It was a massive repudiation of trumpyism and it will continue to gain steam until the election.
Under-performing while managing to take the House is not what is 'impressive'...it is the Democrats being elected because the GOP was not accomplishing a lot....and once they took ownership of the House they demonstrated they did not hear 1 damn thing said by the voters who gave them the House.
The last year has been a continuation of the last 2 years before that - Democrats failing / refusing to legislate, instead focusing on attempting to salvage the failed exposed Obama administration's soft coup attempt against President Trump...
...instead Democrats did the best imitation of
'the three monkeys' regarding the national security and humanitarian crisis on our border, which they have helped create:

HEAR no national security / humanitarian crisis....
SEE no national security / humanitarian crisis....
SPEAK no national security / humanitarian crisis....
NOW, suddenly when the major Leftist media starts reporting horrible conditions at Detention Centers - which the Democrats / House is supposed to adequately fund to prevent this but have NOT been because they have been too busy refusing to acknowledge what's going on, Pelosi and her fellow Democrats who are responsible for the mess have experienced a
'MIRACLE'...

'Praise Obama / Allah / Farrakhan -
I can suddenly SEE...and oh look,
look at the huge national security /
humanitarian crisis that sprang up
'OVER-NIGHT'...damn those
GOP
&
President for not doing
our job of
addressing this problem not adequately
funding the US BPA so they could
deal with the overwhelming flood of
illegals across our border!'
