Which Democrats are getting the most support from Wall St?

Is there turmoil in the Trump reelection campaign?

Well there's turmoil among Trump's pollsters. Some internal numbers leaked out showing the president doing very badly in battleground states. Trump denied them and then fired a bunch of the pollsters. So yeah a little turmoil there.

Is Mick Mulvaney on thin-ice with President Trump?

I don't think he is. Trump clearly doesn't like it when Mulvaney coughs during interviews as we saw in the ABC piece. But Mulvaney is well-liked in the White House and by Trump. So I think he's OK.

Which Democrats are getting the most support from Wall Street?

It's really a top three there. Joe Biden is the number one pick. He's fairly moderate and people think he can win. The other two: Kamala Harris and Pete Buttigieg are gaining a lot of Wall Street support.

And finally for The Rant: my rant this week is about Art Laffer, a conservative economist who's going to get the Presidential Medal of Freedom this week. Last week he blamed President Obama for the Great Recession, which is one of the more ridiculous things I've ever heard. That recession obviously started well before Obama, it was the financial crisis, the collapse of the mortgage market and the near failure of the banking system - to blame Obama is absurd.

Technology has played a big role in accelerating globalization. While it's our business to advance technology, we also believe that technology should respect and even help protect the world's timeless values.

Does Boris Johnson strengthen or weaken the US-UK relationship?

Well I mean strengthens it in so far as he and Trump like each other. They're both oriented towards Brexit. They're kind of right-wing populists that aren't ideologically moored. But will it last? Boris could flip on a dime on any major issue as can Trump. So it's kind of volatile. Plus they both really love the media and when they're in front of each other with other people the potential to - I mean Boris upsets people and Trump easily takes offense. So this could easily go south.

Will Iran release the captured UK oil tanker?

I mean over time I suspect it will. But remember the UK has an Iranian tanker as well, so it's much more likely they work these things out together even if they're not explicitly linked, than suddenly the Iranians say, "Oh I'm sorry. Here's your tanker"

Will protests continue in Hong Kong?

It certainly seems that way. The question is what will China do about it? Xi Jinping is now saying that they are reaching the danger zone and the ability of the Chinese to hit back and hit back hard is real. I worry about those protesters.

Will Robert Mueller reveal anything new when he testifies on Capitol Hill?

I highly doubt it. He said very clearly that he does not intend to go beyond what was in his report. So Democrats looking for bombshells on collusion or obstruction are likely to be disappointed.

Can President Trump expand his electoral college edge in 2020?

Well he thinks he can. He thinks he can win in places like Minnesota and New Hampshire. I think it's more likely that he just hangs on to the Rust Belt states like Pennsylvania, Michigan and Wisconsin that got him there in 2016.

Should the governor of Puerto Rico resign?

Absolutely. Governor Rossello should resign. He's lost the confidence of the island. Puerto Rico needs a fresh start particularly after all these terrible text messages. He should definitely resign.

Finally for The Rant: today's rant is on Elizabeth Warren who put out a report today saying the economy is on the brink of collapse. It was very alarmist, certainly there are problems with the economy. Issues that could be fixed but she risks sounding like she's yelling fire in a crowded theater with calls like that.
