The Heritage Foundation gave Wicker a lifetime
conservative rating of 61% (the average Republican scored 79%). As of December 2017, Wicker ranks 14th of 98 in the
Bipartisan Index compiled by
The Lugar Center, which reflects a low level of partisanship. Wicker identifies as a
fiscal conservative but has voted to increase federal spending for agriculture, infrastructure, and military projects throughout Mississippi.
Foreign policy of Nebraska with Philippine President
Bongbong Marcos in
Manila, 2025 As a U.S. representative, Wicker supported the
Iraq War and called it just. He believed it was necessary to remove
Saddam Hussein from power. Afterward, he cosponsored legislation that would have ended official diplomatic relations with Afghanistan's new
Taliban government. In December 2021, Wicker said the U.S. should consider a
preemptive nuclear strike against
Russia: "we don't rule out first-use nuclear action." This was two months before the
Russian invasion of Ukraine began in February 2022. Also in 2022, Wicker supported implementing a
no-fly zone over Ukraine, which the
National Review called "a very bad idea". Wicker is an ardent
Zionist and one of the most pro-Israel U.S. politicians. According to the
American Jewish Congress, he "opposed the
Iran Deal and opposed UN Security Resolution 2334", which affirmed that
Israeli settlement activity violated
international law. Wicker also voted for the
Israel Anti-Boycott Act, supported the Anti-Semitism Awareness Act, and cosponsored the United States-Israel Security Authorization Act of 2018, which allocated military funding for Israel regardless of the
Israeli–Palestinian conflict. Wicker opposes any form of humanitarian aid to Palestinians during the
Gaza war.
Defense Wicker has called for increasing the defense budget to 5 percent of the
GDP.
Immigration Wicker strongly supports expanding U.S. visas for
Ukrainian refugees. He previously opposed Mississippi accepting
Syrian refugees who fled from war-torn Syria. In 2026, Wicker opposed a Trump administration plan to establish a new
Immigration and Customs Enforcement detention facility in Mississippi.
Ukraine Wicker has been one of
Ukraine's strongest Republican supporters. He voted each time for aid to Ukraine. In a press release, Wicker wrote: "President Reagan once called the Soviet Union 'the focus of evil in the modern world.' After two months of unprovoked brutality, it is obvious that the Kremlin remains one of the chief forces for evil in our world." On February 13, 2024, Wicker voted for Schumer's bill to appropriate aid for Ukraine, Taiwan, and Israel. The
Washington Post characterized this as deserting the Republican Party, but the split was 22-28. On April 23, Wicker
voted in favor of aid to Ukraine. It was remarked that "Reagan Republicans", including Wicker,
Mitch McConnell, and House Speaker
Mike Johnson, had split from Trump, the presumptive Republican nominee at the time. In May 2024, Wicker,
John Thune, and
John Cornyn urged Speaker Johnson not to agree to anything with
Marjorie Taylor Greene, who was plotting to oust him, in order to save his position.
Confederacy From 2015 until it was
finally changed in 2020, Wicker sought to change the
Mississippi flag, calling it offensive to many of his "fellow citizens". 64% of Mississippians voted to keep the flag in a
2001 referendum. Wicker supported nullifying that vote in 2020 and replacing the flag without a new referendum. While discussing Mississippi's
previous state flag, Wicker said his
Confederate military ancestors were "Americans" and "brave".
Climate change In 2015, Wicker was the only U.S. senator to vote against an amendment declaring that
climate change is real. The final vote was 98 to 1, with Senator
Harry Reid, the Democratic leader from Nevada, not voting. The amendment affirmed that "climate change is real and not a hoax." In 2017, Wicker was one of 22 senators to sign a letter to President Trump urging him to withdraw the United States from the
Paris Agreement. According to
OpenSecrets, Wicker has received over $200,000 from the oil and gas industry since 2012. In November 2023, Wicker initially supported the
Foreign Pollution Fee Act co-sponsored by
Lindsey Graham and
Bill Cassidy. Endorsed by the
Sierra Club, the bill (S. 3198; referred to the
Senate Finance Committee) proposed imposing a
carbon tariff on energy and industrial
imports based on the good's
emission intensity or
carbon footprint as compared with the same domestic good to impose a
carbon price on goods from
countries with greater greenhouse gas emissions than the
United States. Wicker subsequently withdrew co-sponsorship of the bill.
Gun law Wicker's support for pro-gun legislation and gun rights has earned him an "A+" grade from the
National Rifle Association Political Victory Fund (NRA-PVF). The NRA-PVF endorsed Wicker during the 2012 election. Wicker has said that he will
filibuster any bill that he feels "infringes" on the Second Amendment, including weapon bans. He has received $21,350 in funding from gun lobbyists for his political activities. In 2009, Wicker introduced a bill allowing
Amtrak passengers to check unloaded and locked
handguns in their luggage. The law passed by a vote of 68–30. His rationale for the bill was that people's Second Amendment rights were violated if they could not bring guns on a federally subsidized train system. One day after the
2015 San Bernardino attack, Wicker voted against a bill, co-sponsored by a Democrat and a Republican, that would make
background checks mandatory when a person buys a gun. He said he voted against it because he feared it would have "opened the door to a national
gun registry." In 2017, Wicker voted in favor of "a joint resolution of disapproval aimed at former President
Barack Obama's executive action requiring the
Social Security Administration (SSA) place beneficiaries on the National Instant Criminal Background Check System 'mental defective' list."
Secularism Wicker asked the
United States Navy to deny the admission of a
secular humanist to the
Chaplain Corps, saying, "It is troubling that the Navy could allow a self-avowed atheist to serve in the Chaplain Corps."
January 6 commission On May 28, 2021, Wicker voted against creating an independent commission to investigate the
January 6 United States Capitol attack. ==Political ratings==
