It looks like the Republican campaigns might be happy to leave Nevada behind them. Mitt Romney has fired one his chief Republican operatives, Brett O’Donnell, late Friday night—apparently due to staff tensions over O’Donnell taking too much credit for Romney’s comeback. O’Donnell had been a former top aid to Michele Bachmannn and had been working as consultant for Romney—and has been credited with turning around Romney’s debate performances. Internal strife within the Romney camp occurred after O’Donnell had taken center stage in the media after Romney’s Florida win. Meanwhile, Newt Gingrich’s Nevada campaign has withered down to just a bare-bones staff working in a tiny rented space in the days before the state’s caucus. One Las Vegas-based Republican operative said Gingrich’s bad week—he was snubbed by the Republican mayor and Donald Trump—reflects the differences of “a four-year campaign versus a four-day campaign.”
