LAS VEGAS -- Republicans in Nevada are poised to do what no one has yet done in the 2012 Republican presidential campaign -- sustain momentum.
Their caucuses on Saturday are likely to deliver a solid victory to Mitt Romney. That would mark the first time this year that a presidential candidate has won two states in a row. After taking Florida on Tuesday by a wide margin, a decisive Nevada win would send Romney rushing into February with wins in three out of the first five voting states and a commanding lead toward winning the Republican presidential nomination.
