(Las Vegas, NV) — Two of the Republican presidential hopefuls are airing TV spots to drum up support for the February 4th caucus in Nevada. The “Review-Journal” says Ron Paul’s 30-second ad touts him as the “big dog” when it comes to federal spending cuts. Mitt Romney’s ad portrays the former Massachusetts governor as a leader and family man. There’s no word on whether Newt Gingrich will air TV spots in Nevada. Las Vegas Sands Chairman Sheldon Adelson recently donated five-million dollars to the former House speaker’s political action committee.
