Oklahoma Rep. Kendra Horn: Horn, a member of the Armed Services Committee, said after Soleimani’s killing, “Though we do not mourn his loss, we must ensure that the United States does not recklessly engage with Iran.” She topped CQ Roll Call’s most recent list of the most vulnerable House members after a surprise win by 1 point in 2018. Trump carried her seat by 14 points. Inside Elections rates her reelection a Toss-up.

Virginia Rep. Elaine Luria: This retired Navy commander flipped a GOP seat in 2018 and is facing a potential rematch against the Republican she unseated, former Rep. Scott Taylor. The military has a big presence in her Norfolk-area district. Luria was one of seven freshman Democrats with national security backgrounds who came out in support of opening an impeachment inquiry in a September op-ed in The Washington Post, and she voted for both articles of impeachment against Trump in December. Luria said in a statement after the vote that the resolution “does not solve the larger problem at hand — which is that we are operating under a nearly two decade-old Authorization for the Use of Military Force (AUMF).” Trump carried her district by 3 points in 2016. Inside Elections rates her race Leans Democratic.

Utah Rep. Ben McAdams: McAdams issued a statement Friday saying he supported Trump efforts to use diplomacy and sanctions “and his recent intentions to de-escalate tensions.” He said the War Powers Act of 1973 “already restricts the president’s ability to engage in military conflict without Congressional authorization,” so he did not support the nonbinding resolution Thursday. “At the same time, I firmly oppose any escalation of hostilities in the Middle East without a coherent and defined plan authorizing the use of military force,” he said. As one of 30 Democrats in districts Trump carried, McAdams is among the most vulnerable incumbents. Trump won his Salt Lake City-area district by 7 points in 2016, and McAdams unseated Republican Mia Love by less than a half a point two years later. Inside Elections rates his race a Toss-up.

Florida Rep. Stephanie Murphy: Murphy, who co-chairs the moderate Blue Dog Coalition, is a fiscal conservative who worked on military relations and national security at the Defense Department under President George W. Bush. She voted against Khanna’s resolution in July and said in a statement after the vote that she opposed the resolution because the War Powers Act already restricts the president’s authority and she is “not prepared to unduly limit our nation’s ability to respond to different contingencies that may arise.” Murphy tweeted after Soleimani’s killing that the general “met his just end,” and she has been critical of the “Monday morning quarterbacking” since then. Murphy flipped a GOP seat in 2016 by 3 points, while Trump lost the district by 7 points. Murphy cruised to reelection in 2018, and Inside Elections rates her bid for a third term Solid Democratic.

New York Rep. Max Rose: Rose criticized the measure as a “non-binding resolution that simply restates existing law and sends the message that war is imminent.” An Army veteran who earned a Bronze Star and a Purple Heart in Afghanistan, Rose said, “I refuse to play politics with questions of war and peace.” He said Trump does need congressional approval to engage in “protracted hostilities or war with Iran.” Rose won his first term in 2018 by 6 points, but he is considered one of the most vulnerable House members since Trump carried his 11th District, which includes Staten Island and parts of Brooklyn, by 10 points. GOP leaders have signaled that their preferred candidate to challenge Rose is Assemblywoman Nicole Malliotakis, who announced Thursday that she raised $306,000 in the final fundraising quarter of 2019 and ended the year with $723,000 in the bank. Rose has not released his fourth-quarter numbers, but his campaign had nearly $1.7 million on hand as of Sept. 30. Inside Elections rates his race a Toss-up.
