A US porn star says she may run as a Republican Senate candidate because the party best represents her "views about sex and money".

Stormy Daniels, who has won scores of awards for her adult movies, claims she has been a "life-long Democrat" but a recent sex-themed party paid for by the Republican Party changed her allegiances.

Her statement followed news headlines that the Republican National Committee spent $US1946 ($2120) last month at a sex-themed Hollywood club that features topless dancers and bondage outfits.

"After months of careful deliberation and [consultation] as to the true nature of my political affiliation I am ready today to declare that should I seek the office of US Senator from the great state of Louisiana that I will do so as a Republican," she said in a statement.
