PM Note - An Errant Tweet with Teeth, Baucus Goodbye, How Dems Lost 591 Years of Seniority

Sheriff Joe Biden Avoids Furloughs - Jon Karl reports: "The VP's office, I am told, is not furloughing anybody and not requiring any staff to take pay cuts. They have found other ways to make the required budget cuts. The VP's office won't say how they have made the cuts.By avoiding furloughs in his own office, Biden also ends up saving himself a few bucks… Biden's office has said, "The vice president is committed to sharing the burden of the sequester with his staff." If his staff faced furloughs, he would do what the president and most of the senior members of the cabinet have done: give back a portion of his salary." http://abcn.ws/11zWCfJ

The Baucus Goodbye - One week after flouting his party with a vote against background checks, six-term Montana senator calls it quits. Jeff Zeleny reports: It is a decision that surprised - and angered - some Democrats, given his vote last week against expanding background checks in the gun debate - a top priority of the Obama administration.

Baucus becomes the eighth incumbent senator and sixth Democrat to announce plans to retire after 2014. His decision to step down could complicate the Democratic efforts to hold its majority in the Senate, giving Republicans an open seat in a reliably conservative state. Yet former Gov. Brian Schweitzer, a popular Democrat, is considering running for the Senate, a party official tells ABC News. http://abcn.ws/12FgWgL (Jeff Zeleny)

So since Joe Biden left the senate to become Vice President, Democrats are on track to lose 13 three plus term senators to retirement and death. That's a huge chunk of institutional firepower. Republicans have lost many of their old bulls too, but as Zeleny notes, the Senate is a changing place.

No kiddin'.

Here's a look at long-serving Democrats (at least three terms) who retired or died with three or more terms since Barack Obama took office.

Their total tenure adds up to about 591 years (with an asterisk for Specter, Rick Klein.)

Baucus: 1979 - 2013 = 36

Harkin: 1985 - 2015 = 30

Levin: 1978 - 2015 = 35

Rockefeller: 1985 - 2015 = 30

Dodd: 1981 - 2011 = 30

Conrad: 1992- 2013 = 21

Bingaman: 1983 - 2013 = 30

Kerry: 1985 - 2013 = 28

Feingold: 1993 - 2011 - 18

Biden: 1973 - 2009 = 36

Lieberman: 1989-2013 = 24

Inouye: 1963 - 2012 (deceased) = 49

Kennedy: 1962 - 2009 (deceased) = 46

Byrd: 1959 - 2010 (deceased) = 51

Lautenberg; 1983 - 2001; 2003-2015 = 32

Akaka - 1990 - 2013 = 23

Byron Dorgan - 1992 - 2011 = 19

Herb Kohl - 1989 - 2013 = 23

Arlen Specter* - 1981 - 2011 = 30 (mostly as a Republican)

591 years ago we were smack dab in the midst of the 100 Years War. Or something.

Brian Schweitzer, the colorful former governor, with his support for the oil and gas industry, his NRA A rating and his bolo ties is said to be interested in running even though he once laughed off senators as senile. Progressives have their eyes set on recruiting him.

Nev. State Sen. - "I'm black. I'm gay" - That's how Nevada State Sen. Kelvin Atkinson told the assembly about his sexual orientation before they voted to overturn a state same sex marriage constitutional ban, according to the Las Vegas Sun. "I know this is the first time many of you have heard me say that I am a black, gay male." http://abcn.ws/11ipwiL

Why Christie is Different - Here he talks off-the-cuff and with great passion about what he thinks makes New Jersey great - Springsteen - "He represents so many of the things that are great about our state: grit and toughness and talent and emotion and talent and success. And you know what everyone else around the country when they would make fun of New Jersey when I was a kid, I'd say yeah, but we've got Bruce. He's ours."

We'll end it there because then Christie starts singing. But it's hard to imagine another pol saying something like that and not sounding like a cheeseball.

WATCH: White House won't join allies in saying Syria used chemical weapons - Three American allies - Israel, France and the UK, have all made the determination, which President Obama said last month would be a "game changer."

Americans Expect Terrorism - There's a new PEW poll out today, reports Chris Good, and majorities of Americans have said they think "occasional acts of terrorism in the U.S. will be a part of life in the future."

After polling in the low-to-mid-60s since 2009, expectations of future terrorism jumped from 64 percent last April to 75 percent today. Pew began its most recent survey of 1,002 adults on Thursday, three days after Tamerlan and Dzokhar Tsarnaev allegedly detonated two bombs in downtown Boston, killing three people and injuring scores of bystanders. - http://abcn.ws/13t2tDw

The Latest on Boston - What is Tsarnaev Saying? - From Ross / Raddatz / Schwartz / Mosk - "For all the power of the two explosions at the Boston Marathon finish line, and for all the dramatic gun fights on the streets of Watertown, and for all the suppositions about the role of disciplined, well-trained terrorists, the college student has reportedly told investigators the whole attack was devised from the Internet. The two brothers, he said, had no direction or financing from governments or rogue groups overseas.

"Authorities tell ABC News they now believe the two foreign-born brothers were inspired to violence by the Internet preaching's of al Qaeda leader Anwar al-Awlaki, the charismatic American-born radical jihadist, who has been dead now for more than a year. They used instructions from an al Qaeda Internet magazine to make their pressure cooker bombs. And Dzhokhar, the younger of the brothers, may not have even known about the plot until a week or so before the attack, sources told ABC News. " http://abcn.ws/15GkiD7

Immigration Bill a "Bonanza" for Democrats? Not Quite - Deep thoughts from Jordan Fabian -

"This morning, Politico published a piece titled "Immigration reform could be bonanza for Democrats" that argues if the bill becomes law "as many as 11 million new Hispanic voters" could transform the electoral map.

"I'm not buying it.

"I covered this ground in a piece last week that sized up the so-called "Undocumented Vote," but it bears mentioning again: believing that immigration reform would be an automatic electoral boon for Democrats is jumping to a rather big conclusion.

"If reform passes, it's possible that several million new Democratic, Hispanic voters will enter the electorate. But the 11 million figure is a vast overstatement. First, it's highly unlikely that all 11 million will go through the entire 13-year process to become full citizens. Many could simply opt for permanent legal status, which does not grant you the right to vote.

"There aren't many solid estimates on what portion of the undocumented will become citizens under this law. Around nine in ten undocumented immigrants say they would apply for citizenship under a comprehensive immigration reform law, according to a recent survey conducted by opinion research firm Latino Decisions. But under the 1986 amnesty law, only about 40 percent of the 2.7 million eligible immigrants eventually earned their citizenship." http:// uninews.us/10xqVaf
