You still believe the “polls”?
Which “polls”, the ones that had Hillary winning?
It is not just a question of believing polls when the disparities are so gross it is a question of believing polls when the margin is narrow. Those who believe narrow polls include Kelly Ann Conway and even Trump's son-in-law who made critical decisions about campaigning in places like Michigan and elsewhere based on very narrow polls.
Those congressmen and senators whom Trump must cajole or intimidate into voting his way also believe in polls and they will want to know whether they must follow Trump or whether they can defy Trump and even run against Trump in their districts.
Polls might not matter to you, but they matter to the Trump campaign, and they matter to national politicians. If Trump has no heft in the polls, he has less power on Capitol Hill. If Trump does not have heft in the polls, you do not get the policies you like.
Yes I believe in polls, not as gospel but as indicators of trend and movement of sentiment -even when I do not like them. Don't you?
