You have some points, but I still don’t see that hurting him. I mean he won the conservative vote tonight by quite a bit. I mean even Ohio, he cleared the state but lost the cities. Most people don’t have any idea who Arlen is....I do because I am from Pennsylvania. I don’t see Obama using Arlen as an attack against Santorum. I heard the Democratic person tonight saying that they hope Santorum is not the candidate because Santorum relates so well to the “working man” (her words, not mine). Anyway, a long way to go before this is decided. We actually still have Alaska to wait on.
If you read his early politics when he was pro-abortion and anti-Reagan (he described Reagan supporters as the "right-wing fringe"), and purely focused on the very moderate parts of the GOP, working only for pro-choice moderates, exactly the kind that he has always continued to support in elections, he mentions his theories on carving out a niche and hanging on to it.
Santorum used to label himself in his campaign literature, a "Progressive Conservative".
The early Santorum is always described as not being interested in issues themselves, but in how to use them.
Before switching to pro-life for his first campaign, this is how he described himself, like Romney he was.
"I was basically pro-choice all my life, until I ran for Congress"
This is his first campaign position paper he wrote to grab pro-life voters, it is less than inspiring.
