The once crowded field of Republican presidential candidates has been winnowed down to three after Marco Rubio dropped out. At one point in time, he looked like he had a real chance of getting the nomination. So what happened? I think he had the following factors hurt him.
Crowded field – There are three roads to the nomination; establishment, right wing or outsider. The only real competition Trump and Cruz had was Ben Carson. Several candidates were vying for the establishment path. Bush spent a lot of time and money going after him. Christie devastated him with the comments about him being programmed and repeating himself.
Lack of experience – Experience doesn’t seem to matter with the other two roads but is important to the establishment.
Immigration – Trump has whipped up the country into a frenzy over immigration. Rubio’s common-sense approach didn’t fit the mood.
Trump attack – Rubio went after Trump in a very clumsy way and had some pretty stupid comments.
This certainly isn’t the end for Rubio. He is only forty-four. There is a governor’s race coming up. There is a long list of candidates that failed the first time out but later got the nomination. He may well be one of them.
