Rubio made a mistake in endorsing Romney now

I’ve covered Rubio for years now, and have found him to be impressive. But if his goal was to help unite the party, he got the timing wrong. By holding out longer, and agreeing to be Romney’s running mate later, he could have served an important function as the bridge between the GOP establishment and the tea party/grassroots conservative base.

But this move seems to deprive Romney of the ceremonial, but very important, gesture of uniting the GOP establishment and conservatives by picking Rubio as a concession.
