In 2022, D'Orsie defeated incumbent Pennsylvania State RepresentativeKeith Gillespie in a primary challenge and went on to win the general election to represent the 47th District unopposed.[6] D'Orsie's success in the primary was viewed as a backlash from the more ardently rightwing faction of the Republican Party because the incumbent had not been as hard-line on conservative issues.[7]
After the Central York School Board published a banned resources list that included books about Black and Latino representation,[9][10] D'Orsie wrote an op-ed in the York Daily Record saying, "the concept of banning books should be intolerable to us." However, he claimed what the board drew up was not a book ban, and any talk of a book ban was a deception perpetrated by the media. D'Orsie also said instead of teaching about "heroic Americans like Rosa Parks and Frederick Douglass" the district's amended curriculum included "pornographic [material]" and "hate filled, so called 'anti-racist' selections that condemn 'whiteness' and pit students against each other."[11]
In March 2023, D'Orsie introduced a bill that would prohibit bias reporting systems at state-funded universities, saying that such systems infringe on freedom of speech.[12]
D'Orsie supports school choice. He argues that a school choice program would benefit students looking for better or more specialized education, rather than continuing to fund what he claims is an ineffective public school system.[13] In December 2023, D'Orsie introduced a bill that would alter Pennsylvania's education funding to be distributed on a per student basis rather than sending funds to individual school districts.[14]
In 2024, D'Orsie sponsored legislation that would protect teachers from repercussions if they refuse to use students' preferred pronouns.[15]
COVID-19 pandemic
D'Orsie opposed mitigation mandates related to the COVID-19 pandemic and referred to such mandates as "unconstitutional" and an "abuse of power." He argued it was for individuals themselves to respond how they saw fit.[2]
