The only reason that weather would be a factor in not showing up is Trump doesn't 't want to get his hair messed up. All other options are crap. Everyone else who actually were there at the cemetery were able to get there in the rain.
That is pure BS.
You, and most folks on this forum know that I am not a fan of Trump.
But the reality is that presidential travel is not a decision that he gets to make as far as details. During that conference in Paris, on that day there were thunderstorms in the destination area. At times the visibility was worse, and the winds much worse than when Kobe Bryant's helicopter crashed. The Marine Corps called off the helicopter flight, at the request of the French aviation agency.
Oh, we will just go in a motorcade. Bull, the Secret Service is NOT going to allow the president to travel in a motorcade along a route not previously planned. They BLOCK freeways in the US for the Presidential motorcade. France had several national leaders in their nation, and they were NOT going to allow last minute major changes such as a US presidential motorcade. That anyone says a motorcade was possible shows only their biases and lack of understanding of reality.
Anyone else remember the time in Connecticut when a senior citizen actually went around blocked streets, through alleys and HIT the car carrying President Ford? The guy was not trying to hurt the President, he just wanted to get to the other side of town. When George W. Bush was President, and scheduled to fly about 90 miles from his ranch to Dallas for a fund raiser. The flight was canceled because of thunderstorms. The Texas Highway Patrol was not going to shut down I-35, and they did not have the manpower available on short notice to close all the entrance ramps. George missed the fund raiser because a 90 mile unplanned motorcade is NOT ACCEPTABLE to the Secret Service. No matter how much the President, First Lady and their staff want to make the trip.
Now, personally, I think Donald Trump's 'loyalty' to members of the active military and veterans is not a true heartfelt belief. He was raised at a time when the intelligence, honesty and motivations of people to serve in the US military was being questioned publicly. And members of the nation's upper class, such as New York City prep school brats, have NEVER considered the masses of people in the military as leading citizens. Not that he actively disdained them, (me included, I enlisted in 1971). Just we were beneath his radar growing up.
And military people have never been in his social or professional acquaintance circles. Even the number of veterans he has personally worked with, met, socialized with, is much smaller on a percentage basis than most Americans.
But he has been told, and found them to be accepting of some of his messages. And they buy Republican BS, such as "Trump gave the military the biggest pay raise in decades." He did not. He signed off on the highest Cost of Living increase in decades FOR ALL FEDERAL EMPLOYEES because of increased inflation, the highest in over a decade.
I don't think Trump's loyalty to active military and veterans is better or worse than President Obama. Just Trump is much showier than Obama. The man does know how to set publicity advantages at times.
And another reality is that even if the story about the trip, or statements or such, are true. It does not matter and will not change a half-dozen votes across the entire nation. My step-grandson is a perfect example of many of the people in the military today, totally buying into Trump's message and BS. We just spent a week in a campground on a USAF base. The Trump enthusiasm is rampant, even among the younger military members.
Traditionally, the youngest members of the military have been Democrat party supporters, because they come from working class families, When I joined, many were from union households. Also a higher percentage of minorities than in the general public.
Over the years, especially since Clinton, that has changed. The young men and women still come from working class, lower middle income families. But the Republican party has been very successful in bringing that group into their circle. Minorities are still a larger percentage of military members than the general public, but they tend today to be from conservative minority families.
Like Trump learned his attitudes about the military as a teenager growing up very isolated from any contact with 'those people', today's soldier, sailor, airman or marine, has grown up in a largely conservative focused environment, and their world view will not change over a news story in media which for over 50 years has seldom focused a positive light on the man or woman in uniform.
