MY CHOICES FOR DEMOCRATIC PRESIDENTIAL NOMINEES

Geriatric Democratic candidates for President:
Bernie Sanders 78 in September (b September 8, 1941)
Joe Biden         77 in November (b November 20, 1942)
John Kerry       76 in December ((b December 11, 1943) - withdrew
Donald Trump 73 in June (b June 14, 1946)
Eliz. Warren    70 in June (b June 22, 1949)
Tom Steyer      62 in June (b. June 27, 1957)

Substitute for Hickenlooper who has withdrawn: Democratic Gov. Steve Bullock of Montana, 53 (b April 11, 1966) who was re-elected to the governorship with 50.2% of the vote when Donald Trump took the state with 56.2% of the vote.  No other Democratic governor accomplished such a feat.

Impressive was Steve Bullock's defeat of Citizens Untied before the Montana Supreme Court as Montana Attorney General; however, the victory was reversed by the U.S. Supreme Court in one of the worst decisions ever made.

So my choices are:
(1) Beto O'rourke (age 46)
(2) Amy Klobuchar (age 59)
(3) Steve Bullock (age 53)

I am investigating Rep. Tim Ryan (OH), 46 (b July 16, 1973) as a possible candidate for President because he seems to be in favor of keeping the ACA and expanding it.  But he thinks that Medicare for all is a dream goal and he is a co-sponsor.

Yes, I realize that all my candidates are having trouble getting traction and are low in the polls.

I am adding some comments on Amy Klobuchar who has been av very productive Senator in the do-nothing Senate:
According to GovTrack, Klobuchar passed more legislation than any other senator by the end of the 114th Congress in late 2016.[28] According to Congress.gov, as of December 16, 2018, she had sponsored or co-sponsored 111 pieces of legislation that became law.[56] During the 115th Congress she voted in line with Trump's position on legislation 31.1% of the time.[57]

As to Beto O'Rourke, since the El Paso shooting, he has re-focussed his approach to running against Trump and is not following the early primary states.  While his new approach may bear some fruit, I'm not sure it will get him the nomination.
