It's their opportunity either to do it or to muff it.
I's say he is doing a fair job of looking religious.
But to show Christ would be to boost things into a whole 'nother orbit.
When Trump talks about how he hopes America to benefit, he's in more of a Christlike mode than when either Cruz or Trump slings mud.
I read where Trump is pulling a negative Cruz ad, and is going to run a positive campaign in South Carolina. Haven't followed up or verified it, but that would be very promising to me.
I hope both start looking at this thing from a higher viewpoint than a mud slinging exercise.
Our past history is that mud slinging between the front runners, any of whom would be acceptable, just opens up the stage for someone mediocre.
In this case, we run the danger of Rubio becoming our Mitt Romney or our John McCain.
