It’s not purely symbolic. If he gets at least 50,000 votes, then the Libertarian Party is ballot qualified for the next four years.
I don't have that much emotional investment in the Libertarian Party, to be honest. In fact, I actually think it's a poor representative of libertarianism, and if anything turns off the public towards both Minarchism and anarcho-capitalism, to the extent the latter is even reflected.
That said, the Sharpe campaign is worthwhile in the sense that it represents at least a strand of opposition to the dismal collectivism that's consumed this state.
Don't be so sure of that. Democrat/Republican state legislatures have a knack for changing the ballot access rules once some third party manages to achieve "Permanent Ballot Access". Saw this happen more than once in Illinois, petitioning for ballot access on behalf of LP.
