Donald Trump is not by any stretch of imagination a great orator, but grammatically, at least tonight he kept things together--and I don't give a damn whether he used a teleprompter or not. His speech clocked in at about 75 minutes, which one reporter said was the longest such speech in 40 years. It was not a dull speech, even if it was overlong.
He must have said "we will make America great again" or one of its congeners about 40 times. Not surprising because repetition is good when dealing with the general public.

Some of his regressive rhetoric about supporting the 2nd Amendment and pride in being endorsed by the NRA.

He reiterated but softened somewhat his rhetoric against Mexicans providing they were legal immigrants. He still promised to build a wall between US and Mexico but did not mention Mexico having to pay for it.

More xenophobia was evident in stating that immigrants reduce wages and displace legal residents (as opposed to legal-newly arrived immigrants). Though not mentioning Muslims specifically he was no less emphatic about not letting masses of immigrant/refugees without "thorough vetting" whatever that means. He does have a legitimate point that terrrorists do slip in unnoticed, such as Mateen's wife and the San Bernadino murderers.

Trump stressed law and order multiple times; he praised the police in general and condemned the police being shooting victims themselves. But he also made a point, although not very emphatic, in regards to unwarranted police shooting of civilians, that no one is against the law. Immediately he commented that Medusa was the greatest law-breaker of modern times, condemning her breaching security with unlawful retention of classified/secret emails. Look for much more of this until Election Day.

In addition to castigating Clinton many times in his speech, he had some nice things to say about Bernie, including how the Dem establishment cheated him out of the nomination. He also co-opted a plank of Bernie's platform calling for financial aid to college students but did not offer specific proposals at this time.

Another possible Sanders co-option was a promise to rebuild America's infrastructure, which would help the economy and create jobs.

Of course the allusions to Bernie were an effort to lure Bernie supporters to his side.

Trump stated very firmly his full support for protection and encouragement of LBGTQ rights. No audible gasps were heard from the audience. Perhaps some elements of the Republican party are willing to join the 21st Century.

Other promises included "drill, baby, drill" with nary a word about climate change. The most distressing issue he raised, which I absolutely judge as horrible is the regressive allowance of "religious" doctrine to influence law enforcement, although he did not so put it that way. However, he did praise evangelicals. Trump also condemned an IRS policy dating back to Lyndon Johnson of denying tax-exempt status to organizations espousing political views.

Although he spoke about being "for the workers" not a mention of labor unions was heard.

He strongly condemned trade deals such as NAFTA, promising to repeal it. He Condemned allowance of China into the World Bank, especially for currency manipulation. His most potent shots were against the TPP, which he vigorously opposes.

True to Republican form, he promised to overthrow the ACA but did not specifying what he would do to replace it. My own feeling is that the ACA, despite its broader coverage and deny insurance refusal for pre-existing conditions, has become a financial trap--the US govt meekly surrendered to the dissolution of insurance co-operatives, thus seeing a dramatic spike in insurance costs--to say nothing about pharmaceutical costs [that is my own critique--Trump did not mention it.]

For all the prior talk about #NeverTrump, there was a tremendous amount of enthusiasm from the delegates, amongst who there were far more African-Americans, Latinos, and Asians as delegates--something very different from the very recent characterization of the Republicans in the recent past.

My take on this is:
1. Despite lack oratorical skills, Trump is a very effective communicator. He did not come off as a buffoon, dislike as you may, his political stances.
2. Hillary's polling has not improved at all since Bernie endorsed her.
3. Trump's polling has increased although not much despite Hillary's massive outspending him in ads in such battleground states as OH, PA, and FL
4. Laugh or sneer as you may, HRC has the fight of her life ahead of her. Trump will not play the gentleman with her. He is already firing the first salvoes and very soon they going to start hitting the target.

Gang, this is going to be a very interesting few months. Hillary will go down in flames once the Repubs really start unloading on her. I'm prejudiced, disappointed, but unless Bernie gets the nomination, Mr. Orangeface will be in the WH.
