"So, I think that Hillary Clinton and every candidate out there should in fact address whether or not they support this T.P.P.," Sanders said.

I agree that it's unlikely Bernie will win, but I think he can pull enough to influence the conversation.  He is also very capable of being loud and intelligent enough to influence a conversation just by being on stage where it's happening.

I will add some links:
Sanders forces delay of trade bill consideration

McConnell said that because of Sanders's objection, the Finance Committee will still meet, but the Senate will have to recess.

Sen. Bernie Sanders, the latest presidential hopeful, issues dire warning to Alabama

If Republicans are successful in passing their 2016 budget, as many as 172,000 Alabamians could lose health coverage, while more than a million senior citizens would be forced out of Medicare.

Why Not Bernie? Iowa and New Hampshire Should Make a Statement and Vote Sanders Over Hillary

However, there's already one Elizabeth Warren Democrat running in 2016. His name is Bernie Sanders. Progressives everywhere should embrace his candidacy, not shrug their shoulders and settle for another "Emailgate" or foreign donor controversy.

Sen. Bernie Sanders to announce presidential bid, reports say

Vermont Public Radio reported Tuesday that he was to announce his bid for the nomination on Thursday. The Associated Press also reported that the self-described socialist was planning on announcing a bid for the nomination, but did not specify a date.

And nothing to do with politics, really.
6 things to know about Bernie Sanders

He now says he is not actively involved in organized religion. But in terms of economic justice, he said, "I find myself very close to the teachings of Pope Francis." He described the pope as "incredibly smart and brave."

From His Website:

Sanders' Agenda. Among his proposals, Sanders calls for free college tuition, a $1-trillion program to rebuild the nation's roads and bridges, government-run health care, higher taxes on the wealthy and publicly funded elections to reduce the influence of the country's rich donors, the Los Angeles Times reported.

  But, I am a realist. Voting for him will be a protest vote. His chances of knocking off Hillary is very slight and he would have even less of a chance in a general.

  I also fear that if he gets "demolished" in the primaries it could be (wrongly, in my view) be spun as a sign the "progressive agenda" is unpopular.

  Many of the things I like about him (beyond policy preferences) are problematic when running for President. One could be pretty much totally aligned on policy but refrain from self-describing as a socialist. I admire that he is that blunt and willingly champions things others would seek to defame by calling socialist, but it does give others a hammer.

   His personality and style  while endearing to me are, putting it lightly, atypical for presidential candidates.  He's cantankerous, candid mixed with impulsive and unwilling to "tone adjust" his message let alone pander.

  I support him and hope he can do a good job of using the campaign as not just a soapbox to force meaningful discussion of issues the others gloss, if not ignore, but maybe even persuade a few more people to agitate for more economic fairness but dancing for joy would require me thinking he could put up a real electoral  challenge. I hope I'm wrong, but I don't.

    I'd still like to see someone, who while maybe not quite as much a true champion of the "common man" with better prospects jump in.

  Who knows, maybe everyone else was just afraid to be first.
