The court of public opinion is what elections are. Cruz doesn't have to be convicted beyond a reasonable doubt. Cruz's base of evangelical voters just have to believe he's an adulterer.
If I didn't think there was anything to this I wouldn't post about it. I don't agree with the conspiracy theories claiming Cruz was working for the GOPe all along. Politically Cruz is much more conservative than Trump, and one of the most conservative candidates who's run since Reagan left office.
But in his personal life... not so much.
If actual evidence finds the light of day at some time in the future, that same public opinion will force him from the contest. It's obvious that we hold Cruz to a higher standard than Trump, who is an admitted serial adulterer, and has been for decades -- in addition to supporting abortion, Kelo, outsourcing, the hiring of illegals, and actively supporting large numbers of liberal politicians.
