Who has the momentum now that the Republican field has winnowed?
Our new national numbers from the past week show that the race remained largely unchanged, although Marco Rubio’s overall number creeped up 2 points from last week to 16 percent. Donald Trump continues to hold a commanding double-digit lead over all other Republican candidates with 36 percent; Ted Cruz remains in second place with 19 percent—just 3 points ahead of Rubio.
These results are according to the latest from the NBC News|SurveyMonkey Weekly Election Tracking poll conducted online from Feb 15-21 among a national sample of 11,662 adults, including 10,386 who say they are registered to vote.
