Why Are Talarico Supporters Still Attacking Crockett Online?

Talarico supporters are still attacking Crockett online. This is three months after the primary with the GOP launching pretty effective attacks on Talarico. Don't they realize they need her voters to win? Crockett received 1 million voters and 46 percent of the vote. Talarico only beat her by 200K votes. Seems very short sided to alienate this large of a voting base.
