so basically this is what you have.... you have hillary supporters driving the protests (aka the dnc FOLKS).
you have a split amongst the progressive/independents - 1/2 are tired of the DNC folks with their "too little too late' hypocrisy of protesting trump while still having supported Hillary (she's not a box of chocolates.. we know VERY WELL EXACTLY what we're getting from her.. its only her "publis personna" that is a box of chocolates which have nothign to do with what she really does behind closed doors) - while the other half is joining the protests b/c of their disgust with Trump on the policies.
we have the GOP who secretly despise Trump but publicly support him b/c its their best chance to get thru as quickly as posible all of their long-wanted agenda items (while happily playign along to allow and enable Trujpm to do his crazy things to distract the public from what the GOP is passing int he background).
As to why people are protesting Trump? I know but I don't know. I find it hypocritial they are now marching in the streets but failed to give an iota of effort to the fraud exected during the primary that BENEFITTED their candidate. True definition of hypocrisy.
