Last week state Representative Mariellen MacKay of Nashua switched her party affiliation from Democrat to Republican.
MacKay is not the first representative to switch parties this session. In February, Rep. Robert Theberge also changed parties from Democrat to Republican. The same month, Rep. Caleb Dyer from Hudson switched his party affiliation from Republican to Libertarian.
Currently, there is no state law that bans a representative from changing their political party while in office, and the issue is not addressed in either the House or Senate rules.
