Eight House Republicans, including the three from districts won by Hillary Clinton in 2016, have been named to the National Republican Congressional Committee’s list of incumbents expected to face tough re-elections.

Members of the Patriot Program typically benefit from fundraising and organizational assistance. The list can be a signal to donors to direct checks to members in need.

“While Democrats continue to call them ‘targets,’ the NRCC will be empowering these members to stay on offense and run aggressive, organized campaigns against their Democratic challengers,” New York Rep. John Katko, Patriot Program chairman, said in a statement Friday.

House Republicans lost a net of 40 seats in last fall’s midterm elections, and the party needs to pick up 18 or 19 seats next year to win the majority back (depending on the outcome of a special election in North Carolina this year). The campaign committee previously announced 55 Democratic targets.

Democrats have a large freshman class to defend next year, including many members in districts President Donald Trump carried in 2016. But the Democratic Congressional Campaign Committee is hoping to expand its majority, identifying 32 GOP seats to target, with an early investment in Texas.
