Donald Trump and Ted Cruz — to borrow a phrase — are “sucking all the air” out of the Republican Party primary campaign.

The two of them arguably are the most divisive, polarizing figures in the GOP. But here we are, watching them slug it out at the top of the primary field. What about the rest of the still-large gaggle of candidates? Huck, Carly, Kasich, Marco, Jeb!, Rand Paul, Santorum, Christie . . . and let’s not forget Jim Gilmore?

Some of those also-rans are actually pretty interesting and experienced individuals. They have executive experience, legislative experience, tangible accomplishments.

They’re being left choking in the dust being kicked up by Trump and Cruz.

I won’t go into why Trump troubles me so much. For that matter, Cruz’s record in the U.S. Senate — such as it is — amounts to next to nothing; he’s been there just three years and began preening for the presidency almost from the moment he arrived.

It is becoming clearer by the day that the GOP race is turning into a two-man contest.

I can hardly wait for the two of them — Trump and Cruz — to begin truly detesting each other.

Is there a major surprise in the offing once Iowans finish their caucus?

Well, for those of us who’ve become addicted to the unpredictability of this campaign, we only can hope.
