[5] He initially endorsed the false Stop the Steal conspiracy theory positing that the 2020 U.S. presidential election was rigged to favor Joe Biden.

[16] During the election campaign, Bolduc ran a television ad attacking Democrats as "a bunch of liberal, socialist pansies", a remark perceived as being homophobic.

[32][33] He opposed the provision in the Democrats' Inflation Reduction Act allowing Medicare to negotiate lower prices for prescription drugs, saying, "Anything the government's involved in, it's not good, it doesn't work.

In May 2021, Bolduc was one of 124 retired generals and admirals who signed an open letter promoting the lie that the presidential election was "rigged" in Biden's favor.

[37] Throughout his campaign for the Republican nomination for U.S. Senate, Bolduc continued to promote the false claim that the election was stolen and that Trump actually won; in an August 2022 primary debate, he said of his signing the May 2021 letter: "damn it, I stand by [it]".

[38] In September 2021, Bolduc criticized General Mark Milley, chairman of the Joint Chiefs of Staff, for reportedly telephoning his Chinese counterpart after the January 6, 2021, assault on the U.S. Capitol to assure him of the strategic stability of the United States.

[41][42][43] "I went through a learning process on the whole thing and came out the other end to it not being a stolen election but one with irregularities and fraud, like a lot of other people on both sides of the aisle", he said in November.

[40] Bolduc opposes legal abortion and hailed the Supreme Court decision overturning Roe v. Wade, calling it an occasion to "rejoice".

He has falsely claimed that COVID-19 vaccines are really "Bill Gates saying we should put [micro]chips inside people" and asserted that the use of face masks to control the spread of the virus "cause[s] more problems than they solve".

Regardless, Trump endorsed Bolduc for the general election, writing on Truth Social that "His opponent is a disaster on Crime, the Border, Inflation, & all else.

[55] Speaking to an audience in North Hampton, New Hampshire, on October 27, 2022, Bolduc repeated the debunked hoax[56] that children are being told they can identify as cats and use litter boxes in schools.

[57] Pinkerton Academy and the Dover School District released statements refuting Bolduc's claim, calling his allegations "entirely untrue".

In a July 2020 interview with WMUR-TV, Bolduc stated that "My big problem with marijuana is that it could be an entry drug and a gateway for our children.

And until we get controls or some sort of system and technology in place for our police to be able to test sobriety of people that that are operating under the influence of marijuana, this is a public safety issue.
