This will be absolutely critical from the Convention until election day. Romney lost the election because he relied on some software program (probably sold to him by some Obama front organization) for his get-out-the-vote effort on election day. Cruz has a ground game that puts Trump's to shame. There are a lot of Trump supporters here that are going to be shocked when half of Trump's delegates desert him on the second ballot while Cruz's delegates hold firm.
None of Cruz’s ground game will matter after the convention ...he will lose in a landslide ...the DIMs haven’t even started on Cruz and the DIMs want Cruz to be the nominee ...you Cruz-bots are in for a rude awakening if you do end up stealing the nomination
