General consenus, on all sides.. is that at least 90%, if not more of the electorate is firmly locked in..committed to one of the candidates, and can't be swayed. So, if there's a maximum of 10% available, and we now have a 5 point swing..according to the article..that means that the one debate swayed 50% of the voters that could be influenced...
“90%, if not more of the electorate is firmly locked in”
Those that say they are locked in assume that nothing will happen to change their minds. Something just happened that was unexpected by many, and certainly by those “locked in” to Obama.
Past counts of locked-in voters are no longer accurate.
