What would happen if trump were to issue an executive order banning only Muslims from entering the United States.?

1) The Supreme Court would strike it down for being unconstitutional.

2) Trump would go to Twitter to whine, cry, and blame everyone but him.

3) The next day, he'd move on.

A person can help Trump to live a more loving and virtuous life by reciting the rosary for him every day, and fasting for his sanctity.

He can't, that is against the US Constitution.

Corruption would flare up and somehow Trump would "disappear" and Hillary would arise like the beast from Revelation

Well, when that happened a republican federal judge struck it down as unconstitutional.

First, religion is a belief and does not necessarily show in a person and people can lie.

Second, it is religious discrimination against the US Constitution.

Third, when he listed countries of banning entry, the courts blocked at least parts of it on religious considerations.

(I would never do that because I am an equal opportunity boobie grabber

This country would be a safer place to live.

The libs would go crazy.

Same thing that happened last time he tried that - the courts would block him.
