Because I–872 does not on its face impose a severe burden on political parties' associational rights, and because respondents' arguments to the contrary rest on factual assumptions about voter confusion that can be evaluated only in the context of an as-applied challenge, we reverse.

Respondents ask this Court to invalidate a popularly enacted election process that has never been carried out. Immediately after implementing regulations were enacted, respondents obtained a permanent injunction against the enforcement of I–872. The First Amendment does not require this extraordinary and precipitous nullification of the will of the people. Because I–872 does not on its face provide for the nomination of candidates or compel political parties to associate with or endorse candidates, and because there is no basis in this facial challenge for presuming that candidates' party-preference designations will confuse voters, I–872 does not on its face severely burden respondents' associational rights. We accordingly hold that I–872 is facially constitutional.
