As we head into the biggest day of the presidential primaries — Super Tuesday — Donald Trump and Hillary Clinton continue to hold commanding leads in their respective primaries, according to our new national numbers from the past week.
In fact, very little has changed, according to our NBC News|SurveyMonkey Weekly Election Tracking Poll for the week of February 22 through February 28, 2016. The poll was conducted online among a national sample of 30,294 adults aged 18 and over.
Among registered Republicans, Trump has hit a new high, and he now commands the support of 40 percent of Republicans. Coming in second is Marco Rubio at 21 percent, and Ted Cruz is third with at 18 percent. Following a debate performance that many thought was his most aggressive, Rubio's support increased 5 percent in the last week, and his support is higher than it has ever been, but he still trails Trump by nearly two-to-one. Cruz continues to hold fast in third place, although his support slipped a percentage and the Texas senator's support is now the lowest it has ever been.
