Can Marco Rubio Take Advantage of His Opening?

Nate Cohn: “He hasn’t quite had his moment in the media spotlight, he hasn’t made big gains in the polls, and he hasn’t earned many endorsements. But the political landscape surrounding his candidacy could not have changed much more in his favor over the last six months.”

“Mr. Walker’s exit is the most obvious and recent development to help broaden the path ahead… Mr. Walker’s withdrawal did more than release his old supporters. It narrowed the choice for mainstream conservative donors, voters and officials who had been waiting on the sidelines. Without Mr. Walker in the race, the choice for mainstream conservatives started becoming clearer. Unless they are willing to support an anti-establishment candidate like Ted Cruz, it’s down to Mr. Rubio and Mr. Bush.”
