I guess, given the incumbent, that the Republican candidates are forced to go back in time to find a role model they can align themselves with, but Reagan? I'm (true to form) not a fan. But here's a quote that sums it up nicely:
Although there was much more to the amazing scandal that nearly ended Reagan’s presidency—including the starring role of neoconservatives who have since masterminded another and worse disaster—the basic outline is clear: Terrorists killed our troops, and Reagan responded by retreating from Lebanon, kowtowing to the terrorists’ sponsors, meeting their demand for advanced weapons and pleading for the release of our hostages.
