Fox Business Network anchor Stuart Varney warned viewers Monday that the crop of potential 2020 Democratic presidential candidates are taking "public policy debate far [to the] left."

Varney said top Democrats expected to make a run at President Trump all have in common their wish to expand the social welfare state and hand out "free money" or entitlements to "entice" voters.

"The current leading Democrats are all pushing giveaways -- your tax money given to favored constituents -- all in the name of 'making us more equal'," Varney said.

Varney said Ohio Sen. Sherrod Brown is calling for "huge increases in tax credits to people who pay no taxes," while California's Kamala Harris is pushing a similar proposal, but with recipients getting paid by the government every month.

He said New Jersey Sen. Cory Booker wants newborn Americans to receive a free $1,000 "baby bond" -- from taxpayers' pockets.

Varney said that other top Democrats may not be pushing for overt tax refunds or giveaways, but that their social program proposals similarly amount to the government spending tax money.

He said Vermont Sen. Bernie Sanders and New York Sen. Kirsten Gillibrand, as well as Elizabeth Warren of Massachusetts may run for president on a platform of free college or free Medicare-for-All.

Taxpayers would be "on the hook for massive costs," Varney warned.

He said that if such candidates take leading roles in the Democrats' 2020 contests, President Donald Trump and the Republicans will face "23 months of political attacks on the president and 'vote for me, vote for free money' tax enticement."

"[They] want to make America more like Europe," he said. "We don't want to copy their obvious failure."
