1. He's leading her in the polls and Trump is not2. He doesn't give her the 1000 points of attack that Trump does (like his crass remarks about women, his body-part, and a thousand other rude and offensive things that make him look as presidential as Dawg the Bounty Hunter.3. He doesn't give her the opportunity to produce his checks written to her campaigns4. He will keep her on the issues which she loses5. He will go after her on her many legal problems better than Trump can (remember this is an accomplished Constitutional lawyer who has won case after case at the Supreme Court)As for the eligibility issue, again he's the the most successful conservative constitutional lawyer that has ran in years (maybe ever), and knows the Constitution better than most judges. However, eligibility is an easy thing to understand. On what basis did he obtain his citizenship? Was it on the basis of birth or of some other naturalization process? It is literally that easy. He's already won the Illinois lawsuit, it was tossed out by a judge IN ILLINOIS Its only muddy when Trumpers do their thing, which holds no water. A liberal judge will declare him ineligible after he has won the nomination, and about 2 weeks before the election. Hillary wins. In Feb 2017 the SCOTUS throws out the case and declares him eligible, too little too late
