Nice.
Still have no idea what the point was.
Any Republican who goes after Trump is necessarily going to be criticizing his "rudeness" to Democrats and the media. That will tick off the very large number of Republicans who are happy that someone is finally fighting back. And that's part of the larger issue -- any Republican who challenges Trump in the primary is going to be resented by Trump supporters, and will be accused of doing the Democrats' dirty work. So even if by some miracle such a challenge succeeded in the primary - which I don't believe is possible given that some state GOP's aren't even going to have a Presidential primary or caucus at all - Trump voters would abandon that challenger in the general election, and he/she would be crushed.
A primary challenge to Trump is overwhelmingly likely to be ineffectual, which is why I'd like to see Mitt try it and get crushed.
In the unlikely event it will have any effect on Trump at all, it will be to weaken him in the general election, and increase the odds of a Democrat winning the election.
