An interesting dissection of support.

Hilton is consolidating support among Republicans, with only 7 percent undecided among R voters.

Porter is popular with the base, but polarizing, and low on Democratic insider support.

Swallwell is the insider pick.

Steyer’s insider support is somewhere in between Swallwell and Porter.

But with the D leadiing candidates, the differences among general support are all within the margin of error of +/- 3.3%

I’m not sure where the article is getting Porter’s D base support numbers from because they aren’t in the linked poll document https://www.politico.com/f/?id=0000019c-d9e2-dd96-a9be-ddfa65c50000
