Midterms always flip parties, no, usually not unless independents get angry. History of the House.

1955-1994 Democrats controlled the House for 40 straight years, winning all those midterms.
1994 flipped from Democrat to Republican
1998, 2002 these midterms, the Republicans remained in control, no flip.
2006 Democrats flipped the House
2010 Republicans flipped the House
2014 Republican remained in control, no flipping
2018 Democrats flipped the House.

Forgetting the 40 straight years of Democratic control of the house, beginning in 1994 the House flipped 4 times, stayed the same 3 times. So why were the Democrats able to maintain control of the House for 40 years? The answer is simple, From FDR until Reagan, those who identified themselves or affiliated with the Democratic Party averaged 45% of the electorate. That dropped to 35% from Reagan to Obama and now stands at 27%. With the Republicans also at 27% today, flipping is much easier depending on independents who now make up 43% of the electorate. The Republicans average around 27% of the electorate from Eisenhower until today.

It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
