You know that not in all states has Trump under performed his poll averages.
Trump exceeded his poll averages in Georgia and Alabama. It won’t matter if Trump takes Florida by 1% or 10%. This state goes to Trump like the rest of Florida neighbor states...like Alabama and Georgia. Moreover, Trump exceeded his poll average in Massachusetts.
In almost every closed primary or caucus, Trump's competitors do much better against him than the polls indicate. In fact, on average, there is an 9-1/2 point swing in the lead away from Trump and toward the closest challenger. To be fair, Kansas skews that number a bit, but only by about 2 points. And Florida is a closed primary.
It won’t matter if Trump takes Florida by 1% or 10%.
True - but if he is within 5% or less in the polls by next Tuesday, I would bet he will lose, based on past performance.
