About 10 states could lose a congressional seat after the 2020 census, and Montana is among the states that may gain one, according to a Virginia political consulting firm's projections.

Election Data Services projects that states like Alabama, California, Illinois, Michigan, Minnesota, New York, Ohio, Pennsylvania, Rhode Island and West Virginia all have seats that could be under threat by 2022.

The lost seats would be reapportioned to Arizona, Colorado, Florida, Montana, North Carolina, Oregon and Texas, which are all growing, according to census data.

The Charleston (West Virginia) Gazette-Mail reports Election Data Services says the drop in the state's population supports longtime speculation that West Virginia will lose a congressional seat by 2022, after the 2020 census.

"What that congressman is likely to see is that his house is going to be put into one of those two districts," said Kimball Brace, president of EDS. "So then the question he would have, is, 'Do I run against the other guy?' 'Do I retire?'"

There are 435 voting members in the House of Representatives.
