The Constitution is Not a “Living, Breathing Document”  —  This morning I heard that one of the other candidates commented that the Constitution is a “living, breathing document."  —  Frankly, I assumed this came from Senator Clinton or Senator Obama.  It is identical to what Al Gore …

Mitt Romney's Lobbyist Connections  —  In a tense exchange with an AP reporter on Thursday, Mitt Romney insisted that even though a registered lobbyist is one of his senior advisers, lobbyists do not “run” his campaign.  —  The claim is part of Romney's new self-styled outsider message …

McCain, You Depress Me  —  My colleague Leon has been “rather stirred” by many things about John McCain, including his “decency about immigrants."  I'm rather stirred by that too — it is my favorite thing about McCain, his capacity to argue that it's a profoundly American imperative …

The president of Florida  —  Just to be safe, I'm going to say right off the bat that Rudy Giuliani might be the smartest campaign strategist in many a year.  —  That way, if the improbable occurs and the former New York mayor wins the Republican presidential nomination, I can say I knew it all along.

Placing the Candidates  —  Interesting chart from the Pew Center.  One piece of bad news for liberals is that it seems that the self-assessed ideology of the American people is still somewhat right of center.  It's also funny how unhinged Republicans' views of Hillary Clinton are.

Nicholas Burns and the Clinton Legacy at State  —  Reports indicate R. Nicholas Burns, the State Department's Number 3 official, will be stepping down.  A career foreign service officer, Burns will best be remembered for his most visible post: the Clinton administration's top State Department spokesman during the mid-1990s.

Southern Blacks Are Split on Clinton vs. Obama  —  ATLANTA — The People's Voice African-American Weekly News in tiny Roanoke, Ala., has not endorsed a candidate in the state's Democratic presidential primary on Feb. 5 — much to the frustration of its publisher, Charlotte A. Clark-Frieson, a Barack Obama supporter.

Callous Conservative  —  After watching Fred Thompson debate his Republican rivals, I have often wondered why he is not in the top tier of candidates.  He seems to have John McCain's honesty, without his razor-sharp edges, and Mitt Romney's conservatism, without his jaw-dropping inconsistencies.

McCain Lies His Head Off; NY Times Asleep at Switch  —  One of the most common-supply-side talking points is that tax cuts always lead to higher tax revenues.  It's not really true (revenues crashed after the 2001 Bush tax cuts) but even if it were, it's misleading: Tax revenues tend to rise …

Hillary Personally Slams Obama Over Reagan Comments  —  The Hillary campaign clearly made a decision to go all out on Obama's Reagan comments today.  Hillary herself just lit into Obama over them in Las Vegas, according to a transcript provided by her campaign:
