From our Constitution (24th Amendment, Section 1)[1]:
>The right of citizens of the United States to vote in any primary or other election for President or Vice President for electors for President or Vice President, or for Senator or Representative in Congress, shall not be denied or abridged by the United States or any State by reason of failure to pay any poll tax or other tax.

Numerous services exist to provide free rides to polling places including some publicly owned transportation options.
The right to vote does not excuse you committing crimes in order to vote and being naked is generally illegal is most of the US which would probably be what prevents you from voting without clothes.
