The Note: Reactions to Howard Schultz could make case for Howard Schultz Yelling at him to go away hardly hurts Schultz's case.

The TAKE with Rick Klein

Howard Schultz may or may not run for president, as he has told the world repeatedly this week.

But the former Starbucks CEO has already managed to do something that almost no one other than President Donald Trump has done in two years' time: drive a sustained debate on both policy and politics.

Schultz's mere suggestion that he would run as an independent candidate has driven the left into fits about what it means to be a spoiler. He has also forced Democrats to defend positions that have become mainstream for 2020ers, notably health care and taxes.

Part of the caffeinated cacophony of anti-Schultz sentiments is designed to drive him away from his presidential considerations, of course.

Still, as his advisers insist, Schultz is listening not to what tweeters and cable news voices are saying but to the atmospherics in which it's all being said. And he may be hearing a much more nuanced message.

His core argument is that neither party is capable of having a real discussion on issues. Yelling at him to go away hardly hurts that case, unless Schultz wants to read it that way.

The RUNDOWN with MaryAlice Parks

A whopping 367 days before the scheduled Iowa caucuses, some of the 2020 Democratic candidates are already lining up endorsements.

Maybe it's not a surprise that Rep. Joaquin Castro, D-Texas, is backing his brother Julian or that Rep. David Trone, D-Md., is endorsing the man who used to hold his seat: former Rep. John Delaney.

But it is a little wild that three Iowa Democratic Party County chairpersons endorsed Delaney's bid for president this week. Sen. Kamala Harris recently scored a couple congressional endorsements too.

It is risky for elected officials to hitch their cart to one person this early in the season, before most voters know everyone who's running. On the other hand, this puts even more pressure on others who are still thinking about running to get in sooner.

The TIP with John Verhovek

They are the only two Republican senators up for re-election in 2020 in states that Hillary Clinton won in 2016, but their answers to whether or not they will support President Donald Trump for re-election could not be more different.

"I'm not prepared to make that decision," Maine Sen. Susan Collins, who didn't support Trump in 2016, told PBS.

"I know what Kamala Harris and I know what Bernie Sanders will do to Colorado, and that's why I'll be supporting the president," Colorado Sen. Cory Gardner told the Independent Journal Review.

Both Collins and Gardner voted for the Democratic plan that would have temporarily re-opened the government last week, and as chairman of the National Republican Senatorial Committee, Gardner bucked the president by refusing to support Alabama Senate special election nominee Roy Moore.

But as it was in 2018 for Republican senate hopefuls in tough races, Trump presents a constant challenge they have to confront.
