No one is saved by election. Election is simply God’s plan. Men are saved by the grace of God, who, through His own free willl, chose to snatch you, a sinner, from the fires that are to come. The scripture does not say that a person that is God’s can leave Him.
No election, no grace, no faith, no salvation - ergo salvation by election.
This would make Jesus ministry moot and the Gospel nonsensical.
