Communication is an important skill any leader should have good communications but it does not automatically mean that anyone with good communication skills is a good leader. Experience and performance matter.
On the topic, in fairness to Erap, he already projected a charismatic character being a "Robin Hood" in both movies and politics that makes him popular but not that good. Communications and wit indeed he does have it that is attractive to the "mass" of our populace but not to majority of the "literates".
Villar is a great choice. His communication skills is still to be fully tested but it will improve in time.
