Will Nevada TV viewers get a replay of the nasty ad war between Mitt Romney and Newt Gingrich in Florida?

The Las Vegas Sun reports Gingrich and Winning Our Future, the super PAC that supports the former House speaker, have yet to buy time in Nevada -- which has fewer and less expensive ad markets than the Sunshine State.

Romney and Ron Paul, however, both have made six-figure ad buys in Nevada, which holds caucuses on Saturday. Rick Santorum released a TV ad for Nevada last night.

Romney cruised to a 14-point victory in the Florida primary yesterday, and was aided by a barrage of ads aired by his own campaign and Restore Our Future, the super PAC that supports him. Figures compiled by Kantar Media's Campaign Media Analysis Group shows 92% of all the Florida spots were negative ads.

Gingrich and Romney head to Nevada later today. Paul, who with Romney is highly organized in the Silver State, has Nevada events throughout the day. Santorum is campaigning in Colorado.

The Romney campaign is already training its sights on Gingrich. Former congresswoman Barbara Vucanovich, who was a member of Gingrich's House GOP leadership team, told Nevada reporters that the former House speaker is "very cocky, arrogant,unreliable."

"I don't want him as my nominee," she is quoted as saying in the Las Vegas Review-Journal.
