Santorum has always been a vanity run. He’s not about to step aside.
I’m afraid you’re right...I was hoping he’d do the honorable thing...but this is exactly why he lost his election prior. He’s from my state and you always hope they represent you well even if you favor another over them. But he’s of the mind to go it the full shot I think....he has high political asperations ,win or loose, and nothings going to deter him from that.
