“First of all, both Ted and I are both running vibrant national campaigns, so the voters are going to have to provide the consolidation — it’s not going to be a deal between candidates,” Mr. Rubio said on “Fox and Friends.” “And that just never happens, and it isn’t going to happen now.”

Mr. Rubio said he’s as angry and frustrated as anyone and that while anger and frustration can motivate people, you have to know what you’re going to do.

“And voters deserve to know how you’re going to do it,” he said. “And right now, all Donald says is, he tells you what the result is going to be, but he refuses to outline how we’re going to achieve these things and voters deserve to know that because this is the most important political job on the planet.”
