This site is very good. It does indeed show right now that Trump would have a hard time beating Hillary but that Cruz would stand a better chance against her.
http://www.realclearpolitics.com/Unfortunately right now it also shows that Trump is probably going to win every state tomorrow except for Ohio and it's close on that one. Cruz doesn't look like he's going to win any of them.
If there is a third party candidate then that will guarantee that Hillary will win and I think that would be stupid to even try that honestly.
Trump certainly was not my first choice. I voted for Cruz in Texas and he won Texas, but he's been a big failure in many ways since. I honestly don't know if he could beat Hillary either. And if Cruz was the nominee, there's no guarantee that Trump wouldn't start his own independent run and take votes away from Cruz.
We are up against a nightmare scenario so I think what we need to do is begin to break down issues where Hillary and Trump the same and what they are different on. I know JTF as an organization can never support Trump but I think as individuals we need to decide (if we're not going to sit this out) whether or not we can vote for one of the candidates knowing that both are not what we would have chosen.
IsraelTrump: Terrible
Hillary: Terrible
AbortionTrump: Claims to be pro-life, but supports funding Planned Parenthood
Hillary: 100% in favor of abortion on demand
Gay marriage/LGBT agendaTrump: Flip flopper on the issue. Sometimes he's for it, sometimes against it. GLAAD doesn't seem very pleased with him though:
http://www.glaad.org/trumpHillary: Used to be against gay marriage but now is 100% in favor of expanding LGBT special privileges
ImmigrationTrump: Claims to want to build a border wall, claims to want to limit Muslim immigration, claims to want to deport illegal aliens
Hillary: Supports path to citizenship for illegals, and keeping families together, and closing private immigration detention centers
SnowdenTrump: Will not pardon Snowden
Hillary: Will not pardon Snowden
Re-electabilityTrump: If elected by both conservatives and liberals, he will need to pander at least a little to the conservatives to get re-elected after four years. He probably won't [censored] the Republican base by nominating his sister for the Supreme Court right away or anything else that would turn all conservatives against him.
Hillary: Will only have to pander to her liberal base. Obama never wavered from his liberalism and it did not hurt him at all.
