Vice President Warren?

I am on record as being unenthusiastic about the idea of a president taking people already in office in the Senate and House as running mates and for cabinet posts, not unless there is such a surfeit of Democrats in both houses to ensure that it wouldn't seriously weaken the strength of a Democratic majority or cause either the loss of a chance to gain control or retain it.

There might be an exception made to Hillary Clinton choosing Elizabeth Warren as Vice President.  The choice would have many pluses.

1.  It would be a very bold choice and historic on top of the historic candidacy of Hillary Clinton for president.  To have two women at the top of the ticket would prove that Hillary Clinton was able to do something bold and brave when there are so many who think she's too calculated.  For the record, that someone who has been under attack in the most vicious possible ways, from the entire range from the far right to the play left would make anyone careful.

2. Elizabeth Warren would make an excellent president.   She is wildly popular with the left and even the play left.   She also has supporters in the middle and even, I suspect, a few who would call themselves conservatives.   Her intelligent populism is exactly what is needed in the country, right now.

3.  It would energize massive support within the Democratic Party and with independents.

4.  Two strong women would be too much for a candidate Trump to keep his mouth shut against, he would make himself ever more unpopular with more people than he's managed to now.   I think he'd alienate even more people and bring out more voters to bury him and his party.   Warren is like a Biden who says what's on her mind but is remarkably responsible in what comes out of her mouth.

5.  If the opposition isn't Trump but Cruz or someone else,  I still think a lot of the above will happen, at the very least they would be hard pressed to avoid making gaffs and regrettable comments that would have a similar effect.

The only down side is, I believe, that in Massachusetts the governor gets to fill appointments for interim Senators.  Thanks to the voters in MA, the MA media and the Democratic establishment giving one of their more proven election losers a chance last time, it would be filled by the Republican Charlie Baker.   He wouldn't likely appoint a grunting, knuckle-dragging paleo-Republican but whoever he appoints can be counted on to toe a Republican line like the phony moderate, Susan Collins does.  It's the genteel thugs who do the most damage.   A President Hillary Clinton will need a Democratic Senate and House to get anything done, any Democrat with a Republican Senate will have a rough time getting appointments filled,  not to mention laws passed.
