According to the Guardian, Baldasaro is "known as one of the most conservative—and controversial" members of the New Hampshire's 400-member House of Representatives. Baldasaro led the fight against same-sex marriage in New Hampshire. In the 2012 Republican presidential primaries, Baldasaro supported Texas Governor Rick Perry. At a Republican primary presidential debate in 2011, the audience booed and jeered a gay Marine who had submitted a debate question about the "don't ask, don't tell" policy. When asked about the incident, Baldasaro said that he was "disgusted" by the Marine and said: "I thought the audience, when they booed the marine, I thought it was great." Baldasaro, who was criticized for the remarks by the Nashua Telegraph, defended his comments in the media, stating that it is against Department of Defense regulations to wear a PT uniform at a partisan event. Baldasaro considered running for the United States Senate in the 2014 election but did not enter the race. In late December 2015, in response to a Facebook post made by DemocraticState Representative Amanda Bouldin's supporting breastfeeding in public and opposing a New Hampshire bill that would criminalize the exposure of women's nipples or breasts in public, Baldasaro wrote on his Facebook page, "Amanda, no disrespect, but your nipple would be the last one I would want to see. You want to turn our family beaches into a pervert show." Baldasaro refused to apologize or retract his remarks. The incident prompted Republican House speaker Shawn Jasper to ask state Representatives "to act with dignity, to act with respect" in his remarks the following month at the opening of the 2016 legislative session. Baldasaro was an advisor to Donald Trump when Trump was the Republican nominee for president in the 2016 election, and regularly appeared with him at campaign events. Baldasaro was the co-chairman of the Trump campaign's national veterans coalition. Baldasaro was a delegate at the 2016 Republican National Convention. At the convention, Baldasaro called for the execution of Democratic presidential candidate Hillary Clinton, accusing her of treason and saying she should be "put in the firing line and shot”. Baldasaro declined to apologize for his remark and then repeated it. New Hampshire Republican Senator Kelly Ayotte responded that “This kind of rhetoric is totally irresponsible, it has no place in our society, and violence should never be encouraged against anyone.” The Secret Service investigated Baldasaro over the remarks. However, in 2019, following the remarks, Trump praised Baldasaro at a rally in Manchester, New Hampshire. Baldasaro also was named a New Hampshire co-chair of Trump's 2020 reelection campaign. On December 5, 2018, Baldasaro began serving his seventh term in the House. Republican caucus leader Dick Hinch has appointed Baldasaro as the Minority Floor Leader for the 2019-2020 legislative term.
