Longest serving Governors in history?

[bgwah]

Rick Perry will have served as Texas Governor for 10 years by the time his current term is done.

The only other current Governor who has served longer, and only by a matter of days, is ND Gov. Hoeven, who will undoubtedly be a Senator come January...

If Perry gets another term, which appears very possible, he could get to 14 years if he finishes the whole thing.

When is the last time anyone served as Governor for this long?

I'm aware of several people who have served longer, but only non-consecutively. LA Gov. Edwards, for example, served a total of 16 years, but he had three separate tenures. There is also SD Gov. Janklow, who again served 16 years, but during two separate tenures. In Oregon, popular former Governor Kitzhaber, who served two terms from 1995-2003, was term limited from seeking a third term in the 2002 election. However, Oregon's term limits only apply to consecutive terms. Kitzhaber is thus running for a third term this year. If he were hypothetically elected this year (he should win easily) and again in 2014, he could also achieve 16 years non-consecutively.

But what about the longest single Governorship? I know there were some 12+ year guys in the late 18th/early 19th century. Has anyone served more than three terms (12 years) consecutively in the past century?

Who are the longest serving Governors in the U.S. overall, under each standard?

Ugh, yeah I forgot about him.

I also forgot about Wisconsin's Thompson, who also served 14 years, lol.

Well, no GA Governor has served overt two terms. But these might be of interest:

-Zell Miller. Served as Lt. Gov. for 16 years from 1975-1991
-Thomas B. Murphy. Served as Speaker of the GA House for 30 years, 1973-2003. The longest serving Speaker in the Country.

Hah, well Washington has only had four State Auditors since 1905, including one who served for 32 years (1933-1965).

We also had a Lt. Governor who served for 32 years (1957-1989).

Looking through Wikipedia, here are some older ones:

18 years - George Clinton (New York, 1777-1795) + 3 more (1801-1804) for a total 21
15 years - Arthur Fenner (Rhode Island, 1790-1805)
15 years - Jonathan Trumble (Connecticut, 1769-1784)
14 years - William Livingston (New Jersey, 1776-1790)

George Clinton wins under both methods as far as I can tell, though I've only checked the NE so far.

I believe that George Wallace might hold the record for greatest total number of years as Governor, even though his term were non-consecutive.

He is also only 16 overall. 17 if you want to include Lurleen's tenure.

Governor Albert Ritchie of Maryland served for 25 years as Governor between 1920-35.

memphis is right,  you meant 15 years. Interesting, nonetheless. And narrowly defeated for a fifth term.

The longest (consecutively) since George Clinton, so far.
