In a news release Tuesday, Paul shunned the Republican nominee and announced his support for Johnson, a former Republican governor of New Mexico who ran for president as a Libertarian in 2012 and 2016.
Johnson and Paul share an enthusiasm for extremely limited government. Rand calls Johnson a true fiscal conservative and praises his leadership in opposing government overreach.
Johnson backers are pressuring Republican Mick Rich to drop out of the race against incumbent Democrat Sen. Martin Heinrich of Albuquerque.
Rich is a commercial construction contractor and political newcomer. Tuesday is the final day for candidates in New Mexico to withdraw their names from the general election ballot.
