Senators as presidential candidates: Why Rubio, not Cruz, is GOP’s best chance

Since the 17th amendment that required senators to be directly elected by the people passed in 1913, the only senators to go from Capitol Hill directly to 1600 Pennsylvania Avenue were Warren Harding (1920), John F. Kennedy (1960) and Barack H. Obama (2008).  Each possessed the most important political asset of any senator: serving in relative public anonymity as senators. Between them they served a combined total of 18 years. Only Kennedy actually stood for re-election. Once safely in office, JFK began running for the Democratic presidential nomination on his war, not Senate, record. Obama, elected to the Senate in 2004 after losing a race for Congress, began running for president in 2007. His campaign centered on his opposition to President George Bush’s invasion of Iraq while he was a sitting state senator in Springfield, Illinois.

Compare their thin-bare legislative records to the many losing Senators in the post WW II era. Ohio’s Robert Taft, the Republican party’s leading conservative thinker (1948 and 1952); LBJ (Texas), considered the greatest majority leader in the 20th century (1960); “Scoop” Jackson (Wash.), regarded as the Democrats' top authority on military matters (1976); the legendary GOP party leader Howard Baker (Tenn.) (1980); and Foreign Relations Committee Chairman Joe BidenJoseph (Joe) Robinette BidenKerry: Trump attacks on Biden are 'unbecoming of a president' Biden rips Trump immigration policy: 'One of the darkest moments in our history' The Hill's Morning Report — Trump and Congress at odds over Russia MORE (D-Del.) (2008), were defeated in nomination battles. Barry Goldwater (R-Ariz.) (1964), then the father of the conservative movement; George McGovern (D-Minn.) (1972), then the leader of the anti-war, progressive movement; GOP Majority leader Bob Dole (Kansas) (1996); Senior Democratic lawmaker John KerryJohn Forbes KerryKerry: Trump attacks on Biden are 'unbecoming of a president' Congress has five ways to show American power against Russia Sunday shows preview: Questions linger over Trump-Putin summit MORE (Mass.) (2004); and long-serving Republican leader of the party’s moderate wing John McCainJohn Sidney McCainThe Memo: Summit fallout hits White House Graham: Biggest problem is Trump ‘believes meddling equals collusion’ Obama, Bush veterans dismiss Trump-Putin interpreter subpoena MORE (Ariz.) (2008), were all defeated in the general election.

Thus our 100 percent, time-tested, iron law of presidential politics: If a senator becomes defined in the public mind through legislative service or as an ideological movement leader, he or she cannot go directly to the White House. Why? Senators become known either by legislative accomplishment, or for being cause-oriented and controversial. Neither is a proven path to the presidency from Capitol Hill. Serving quietly, in relative anonymity seems the only sure path from the senate to 1600 Pennsylvania Avenue.

This historic pattern suggests that Sen. Ted CruzRafael (Ted) Edward CruzDem leaders fend off calls to impeach Trump Cruz: 'I'm glad' Disney fired James Gunn over 'horrible' tweets Washington needs to end hidden inflation tax on our capital gains MORE (Texas) is a sure-loser, if nominated by the GOP, whereas Marco RubioMarco Antonio RubioRubio: Crisis in Nicaragua could lead to civil war Release of Carter Page surveillance documents reignites debate Graham: Warrant for Carter Page surveillance was 'a bunch of garbage' MORE (R-Fla.) just might be the kind of senator who can win. Cruz is the latest Senate cause guy, eager to stand alone on the floor of the chamber.  The Texan’s 21-hour made-for-talk radio filibuster against Obamacare, and his “defund or die” shutdown strategy, made him the ideological darling of talk show economics. That formula requires constantly finding ideological purists with new conservative halos to maintain the audience necessary to charge lucrative advertising rates. Now comes Cruz's Christian-only Syrian refugee legislation. This works brilliantly for talk show jockeys and their radio economics. But it has proven to be the losing image for a presidential candidate.

In stark contrast is the junior senator from Florida, Marco Rubio. Attacked for a lack of substantial experience in the Senate  - he has served less than four years – as well as for a thread-bare legislative record and even missing many floor votes, Rubio might just have the right profile for a U.S. senator seeking the presidency. Although acknowledged as smart, he clearly has not established himself as a major force in the legislative process, and although known for some strongly conservative views he is not perceived as a cause-oriented figure or an ideologue. Rubio thus has the right amount of empty space to create his own presidential campaign persona.

It is of course a fair question whether indeed Senate experience and legislative accomplishment should matter more than they have historically. The 2016 election seems tailor-made instead for a GOP governor or former governor. But governors are the ones dropping out as Cruz and Rubio are making their moves. If the GOP contest morphs into Donald TrumpDonald John TrumpTrump warns Iran's Rouhani: Threaten us 'and you will suffer' Pompeo: Iran's leaders resemble the mafia NYT's Haberman: Trump 'often tells the truth' MORE, Cruz, and Rubio leading the pack, as many now predict, it will be fascinating to see whether Republican voters go with the outsider, the cause guy, or the one who by historical standards looks the most electable.
