Yes, they do.
Why? Because you can.
However the Republicans are much more blatant about it.
America’s electoral system has been rigged. Not by the Russians, but by good ole fashioned gerrymandering.

1. North Carolina
An absolute shitshow of districts that are long and thin for the Democratic areas.
Of the top 10, nine are Republican. Maryland is the only one in there that's Democratic.

"
REDMAP (short for
Redistricting Majority Project) is a project of the
Republican State Leadership Committee of the United States to increase
Republican control of
congressional seats, as well as state legislatures, largely through manipulating electoral district boundaries. The project has made effective use of partisan
gerrymandering by relying on previously unavailable
mapping software, such as Caliper Corporation's
Maptitude to improve the precision with which district lines are strategically drawn.<a href="
REDMAP - Wikipedia"><span>[</span>1<span>]</span></a> The strategy was focused on swing
blue states like
Pennsylvania,
Ohio,
Michigan,
North Carolina, and
Wisconsin, where there was a
Democratic majority, but which they could swing towards Republican with appropriate redistricting. The project was launched in 2010 and estimated to have cost the Republican party around US$30 million."
The Republicans literally made it a national policy to CHEAT.
