Arlen Specter was endorsed in 1996 by Santorum for President when Arlen went to Iowa himself.
Then Santorum endorsed Arlen Specter over Pat Toomey in 2004 during the US Senate.
But later that year Santorum who is a darling of National Right To Life, a GOP establishment group, went to Alaska.
His mission was to twist the arms of Alaska Right To Life so they would support “pro-choice” Lisa Murkowski for US Senate.
Santorum pushed for them to endorse Murkowski over pro-life Mike Miller. Miller was supported by the then mayor of Wasilla, Sarah Palin.
They must be putting Santorum in to try to pry votes away from Palin on behalf of Willard M. Romney.
That’s how desperate the GOP Washington Beltway Establishment is.
This snarky comment reveals much about your politics. National Right to Life, a GOP establishment group?!
Your post had no link and just didn't seem to fit Rick Santorum, so I searched for this. Here's a Juneau Empire story on this matter. IMO, Nextrush makes fast and loose with the facts. Note that Chris Smith also appealed on behalf of Murkowski. The real race was between Murkowski and Tony Knowles(D) with Jerry Sanders trying to be a spoiler as an independent. [Whoever Mike Miller is, he never had a prayer]. Santorum was trying to keep the GOP represented in the Senate (unlike how well we're doing now). Here is the statement of Alaska Right to Life President Ed Wassell on Santorum's endorsement of Murkowski (from the article):
Wassell said Santorum's basic message was that Murkowski may not be the best candidate, but was worthy of support.
