Cruz Grabbing Support from Collapsing Rubio

Nate Cohn: “There was a big shift in the Republican race over the last few days: Ted Cruz surged, almost entirely at Marco Rubio’s expense.”

“The Cruz surge was the clearest sign yet that Donald Trump might indeed be at a disadvantage in a one-on-one race. Viewed that way, Saturday was a bad night for Mr. Trump. Not only did the primaries and caucuses that day suggest he could lose if the field dwindled to one opponent, but the results also probably made a one-on-one race more likely by elevating Mr. Cruz at Mr. Rubio’s expense.”

“But not all is gloomy for Mr. Trump. The results made it likelier that he would face a candidate, Mr. Cruz, with serious limitations in the blue states that dominate the second half of the primary season.”
