Why it matters: Several advisers in Trumpworld told Alayna that Warren is arguably a better candidate in terms of being quick on her feet and prepared on a debate stage. But those advisers say her liberal stances on some issues and her “likeability” problem with segments of general election voters make her weaker against Trump than even a Biden hindered by gaffes, generational dissonances and a son with personal drama and a lobbying record.

“He still feels safe,” a Trump campaign adviser said of how U.S. voters perceive Biden. The former vice president is not saying “crazy, radical” things and “people think Biden will bring some semblance of normalcy.”

The president’s supporters also insist that Warren would put more states in play than most anyone: “She makes winning Wisconsin a sh*tload easier, and Michigan — are you kidding me?!” a former White House official said.

To date, the attack strategy Trump’s team has tested most successfully with voters who backed him in 2016 is painting Dem candidates as socialists, and it’s a lot easier to stick a socialism tag on Warren than on Biden.
