PM Note: Will There Be a Portman Effect?, Boehner's Response, Mitt Admits Mistakes

Coming up Sunday on This Week with Martha Raddatz - John Boehner

A first taste - Boehner told Raddatz that he could not envision a situation where his views would shift on same-sex marriage - even if one of his children came out as gay.

"Rob's a great friend and a long-time ally. And I appreciate that he's decided to change his views on this," Boehner said. "I believe that marriage is the union of one man and one woman…It's- it's what I grew up with. It's what I believe. It's what my church teaches me. And I can't imagine that position would ever change."

Other Politicians Who Have Changed Positions on Same-Sex Marriage -

Rob Portman and the Same-Sex Marriage Tipping Point- Sen. Rob Portman's public and carefully choreographed endorsement of gay marriage is something of an anomaly, at least among Republicans. He's the third Republican now sitting in federal office to endorse same-sex marriage. More than 100 high-profile Republicans recently urged the Supreme Court to strike down California's Prop. 8 and allow gay marriage in that state. But only two of them - Rep. Richard Hanna, R-N.Y., and Rep. Ileana Ros-Lehtinen, R-Fla. - are in federal elective office. If Republicans are going to keep pace with public opinion, he won't be the last.

After years of states' passing constitutional bans prohibiting gay marriage, public opinion has shifted and if a conservative lawmaker from a state whose same-sex marriage ban helped hand George W. Bush a second term can support same sex-marriage, it means the floodgates are opening. Even Foster Friess, the GOP megadonor who backed Rick Santorum's presidential campaign, has evolved on the issue. Santorum, not so much.

Flashback - When Will Same Sex Marriage Be Irrelevant? - Jonathan Karl asked Cheney in July whether gay marriage would be a relevant issue in the future. "I don't know that it's relevant now. You know?" Cheney said.

How Other Republicans are Shifting - Certainly there will be social conservatives still loudly opposing same-sex marriage in the party. But it is worth noting that even as their personal opinions differ, Rubio's policy position is not unlike what President Obama's was when he personally endorsed gay marriage in May of 2012. Obama said then that there was a healthy debate on the issue going on in the states.

Making Pills Less Snortable - A bill introduced in the House of Representatives would ban from circulation certain pharmaceuticals that could be easily abused as recreational drugs. The proposed legislation is aimed at variants of addictive painkillers and other oral medications. Reps. Bill Keating, D-Mass., and Hal Rogers, R-Ky., made the announcement at a news conference on Capitol Hill today. Keating said the legislation, if passed, would help curb a "silent epidemic" of prescription drug abuse. (Matthew Larotonda)
