My main point was that primaries are the times to sort out each candidate that is running, and in the end the most "popular" will win out. I understand for idealogical reasons some may never support others, but for me, I will vote for the eventual nominee, but in the primary I am voting for who I feel safest with, and who I have the most confidence can win the general election.
I was also just pointing out that the article really didn't have any "meat" to refute.
