Politics in the south in a funny thing.
Bush was born in MA, but because he was governor of TX, his father is a "resident" of TX for tax purposes, and his little brother is governor of FL, then he is a "good old boy?".
His mother comes from an aristocratic New England family. Her distant cousin was President Pierce, her maiden name, and was a strong supportor of slavery, although he retired to Vermont. During his administration (1852-56), he did little to avert the tensions that precipitated the Civil War (1860-65).
Southern politics is not well understood by most of the United States and the rest of the world. This is a problem that was present from before the United States was formed, and is the cause of the Civil War, and continues to be a problem today.
My sister did her specialty training in Augusta, GA and lived in Columbia, SC, for three years. The Confederate flag still waves there over (or near) the State House. The ruling classes in SC are very proud of the fact that SC was the first colony to declare war against King George III in 1773 and again the first state to secede from the Union in 1860. My sister told me it was an eye-opener, because history as taught in regular school does not cover the Southern perspective. Her husband was born in Shreveport, Louisiana, so she was accepted as part of the community during her stay there. He was a "southern boy, one of our own".
So, let it be said that there are two distinct cultures in the United States: Northern and Southern.
There is even a cultural difference between the border states as Delaware, Maryland, Tennessee, Kentucky and Missouri which were neutral during the Civil War and the Deep Southern States which had large plantations. There are no large cotton fields in the border states to pick here, so there were few slaves held here. The State of Virginia seceded from the Union, but the poorer Western region of the state "seceded from the Secession" and rejoined the Union as a separate state because the region was different in culture and economics from the rest of the State of Virginia which held large cotton plantations.
As far as respecting the President is concern: like it or not, he does represent my country. I did not vote for him, nor do I like the circumstances under which he was "(s)elected" but his office represents the country I call "home". Conversely, during the Monica Lewinsky scandal during the Clinton administration, I felt that I could not even discuss the presidency or current events with my third/fourth/fifth grade students, so I suspended that part of my curriculum until it blew over. But if Bill Clinton had graced my class with his presence, we would have shown the President the respect for his Office that he deserved. Furthermore, I am old enough to remember the 1960 election which elected JFK from the late Chicago returns which were suspected to be from registered voters posthumously. My parents did not vote for him either.
The U.S. is full of suspicious elections, free as they are supposed to be.
