Not likely. The weather at Reagan's 2nd inaugural (January 1985) was bitterly cold, so cold that all DC residents were advised to stay indoors if at all possible. The Inauguration wasn't postponed; Reagan's swearing-in took place in a private ceremony indoors and the Inaugural itself took place inside the Capitol.
But you may be right, if the weather is inclement and the organizers decide that crowds are of such a size that no public building would be available to handle them, it may be "rescheduled."
I am not advocating him in ANY way shape or form, he is a tic stuck in our scrotum and if you yank him out now his head will pop off and create a worse infection.
I once had a tick stuck in my arm. I removed it by holding a lit match next to its behind. The little bugger backed out quickly (head and all) and I was then able to burn it to a crisp. :)
I have a confession to make, that really happened to me when I was a teen, and it did get infected because the head stayed.
So....
We cannot yank the blod engorge Marxist tick lest we leave behind the head and jaws.
We can perform hit and run tactics against his followers, they are already reaching a critical mass of astonishment that the promises made to make them followers was false lies to support their demi-god at their expense.
I remember watching the sequel to the classic movie The Guns of Navarone where they had but a limited amount of explosives to crack the dam, but if placed properly and set off in stages it creates shockwaves combined with the weight behind it creates fissures and cracks and ultimately failure.
Obama has a massive amount of weight about to be lowered onto him immediately after the inauguration.
Israel will ignore him and the public will deride and castrate him because he has failed to prevent Israel from Attacking Iran. That is a near certainty, might be happening this very moment for all I know.
A massive sea oil refinery platform was launched years ago in the North Sea, huge was an understatement, somebody welded a gusset for a sea hydrophone in the wrong place and a crack started, it sank the rig.
We can hammer the wedge in his cracks and no amount of infinite monkeys will save him from sinking.
As I so fondly remember the scene of the movie Titanic, where the chairman of the White Star Line claims its unsinkable, and the reply, “If its made of iron(or steel) it will surely sink”.
