As Sen. Elizabeth Warren (D-Mass.) surges in the polls to a consistent second place behind former Vice President Joe Biden, heightened attention has exposed her to more serious efforts to attack her by other members of the Democratic field.

Driving the news: In recent days, Biden and Mayor Pete Buttigieg criticized Warren for dodging questions about whether her Medicare for All proposal will raise taxes on middle-class Americans, according to USA Today. Both Buttigieg and Biden oppose abolishing private insurance under Sen. Bernie Sanders' Medicare for All plan, and instead favor a "public option."

  • "You can’t beat Trump by not being straightforward about what it’s going to do,” Biden told a Warren supporter at a campaign event.
  • "I think that if you are proud of your plan and it's the right plan, you should defend it in straightforward terms,” Buttigieg told CNN.
  • For her part, Warren has contended that the question shouldn't be whether taxes will be raised — it should be whether the total health care costs to American families will increase.

According to the AP, Warren has also faced backlash from Sanders supporters after the Working Families Party — a key progressive group that backed Sanders in 2016 — chose to endorse her instead.

  • The Biden campaign has also quietly suggested that Warren has purposely declined to release tax returns from her years doing corporate legal work as a Republican because "she doesn’t want scrutiny on her sources of income in the years before she established herself as a consumer champion," per the AP.

Between the lines: Warren's increased stardom could take pressure off Biden, who — especially on the debate stage — has been the target of candidates looking for their breakout moments.

Biden's inflation danger

President-elect Joe Biden's $1.9 trillion stimulus proposal has economists and bullish market analysts revising their U.S. growth expectations higher, predicting a reflation of the economy in 2021 and possibly more booming returns for risk assets.

Yes, but: Others are warning that what's expected to be reflation could actually show up as inflation, a much less welcome phenomenon.

CES was largely irrelevant this year

Forced online by the pandemic and overshadowed by the attack on the Capitol, the 2021 edition of CES was mostly an afterthought as media's attention focused elsewhere.

Why it matters: The consumer electronics trade show is the cornerstone event for the Consumer Technology Association and Las Vegas has been the traditional early-January gathering place for the tech industry.

The FBI is tracing a digital trail to Capitol rioters

Capitol rioters, eager to share proof of their efforts with other extremists online, have so far left a digital footprint of at least 140,000 images that is making it easier for federal law enforcement officials to capture and arrest them.

The big picture: Law enforcement's use of digital tracing isn't new, and has long been at the center of fierce battles over privacy and civil liberties. The Capitol siege is opening a fresh front in that debate.
