John Avlon expects a long race:
Play around with the CNN delegate calculator and you can see that even if Romney were to win every contest going forward with 100 percent of the delegates (that’s called kickin’ it North Korea-style) he still wouldn’t reach 1,144 until April 3. Under a similar extreme scenario, it would take Rick Santorum until April 23. Here’s the real kicker: If Romney and Santorum were to split the delegates going forward and each were to carry five of the 10 all-or-nothing contests, neither candidate would win enough delegates to clinch the nomination.
