Persuadable

Near-synonyms: amenable; movable; reachable

‘Once Lady Anna is here, the bridegroom will be mellow, persuadable, and you will press your advantage.’

The survey vindicated the politician's assertion that there were few persuadables among his constituents.

So when you're thinking about how does this affect the persuadables, which may be a small percentage of people out there, I think the most effective elements that we saw in this first hour for the persuadables were: William Barr and Ivanka Trump and that video of what really did happen in that attack on the Capitol, the viciousness of it, the violence of it, the planning of it, the relentlessness of it, and that, that is what Donald Trump refused to stop.
