His sound bites for the common good and against corporate greed havenโ€™t changed. But facing the biggest test of his political career, U.S. Sen. Bernie Sanders, I-Vt., said the stakes had never been higher.

The Vermont independent toured his home state this Labor Day weekend in support of a $3.5 trillion budget bill that, if adopted by colleagues now arguing over its price tag, would be the largest federal social spending plan in the nationโ€™s history.

โ€œThis bill will be the most consequential piece of legislation for working people, the elderly, the children, the sick and the poor since [President Franklin Delano Roosevelt] and the New Deal of the 1930s,โ€ he said in Springfield on Saturday as he kicked off a five-town tour that drew more than 2,000 people there and in Brattleboro, Middlebury, Newport and St. Johnsbury.

The bill could bring life to a host of Sandersโ€™ longtime hopes, including universal pre-kindergarten, free community college, paid family and medical leave, energy efficiency and climate change improvements, price reductions on prescription drugs and the largest-ever expansions of affordable housing and Medicare health insurance to cover dental, hearing and vision care.

โ€œMy Republican colleagues are going to tell you that Bernieโ€™s plan is going to raise taxes,โ€ Sanders said. โ€œThey are right. We are going to raise taxes โ€” on the billionaires and large corporations โ€” but nobody in America who makes less than $400,000 a year will pay a penny more.โ€

Sanders, having traveled the country the past two presidential elections as a candidate, spoke this time as chair of the Senate Budget Committee thatโ€™s drafting the plan. As such, the self-described democratic socialist is drawing national attention for what New York Times columnist Maureen Dowd calls his โ€œascensionโ€ as โ€œa key member of The Establishment.โ€

โ€œThe Vermont Independent, often depicted by the media and Republicans as well to the left of his party, is showing a conciliatory side,โ€ Politico recently affirmed. โ€œThe 79-year-old is one of the most powerful people in Democratic-controlled Washington.โ€

But Sanders, set to celebrate his 80th birthday Wednesday, acknowledged he had his work cut out for him.

โ€œSadly, the $3.5 trillion reconciliation bill will, in all likelihood, not get one single Republican vote,โ€ he said.

And Democrats, who hold a slim majority in both chambers, have yet to unite around the plan. 

U.S. House Speaker Nancy Pelosi, D-Calif., has promised moderates a vote on a separate bipartisan infrastructure bill by the end of the month, but progressives say they wonโ€™t support it until the larger budget bill is passed.

Enter U.S. Sen. Joe Manchin, D-W.Va., who reiterated last week that heโ€™s wary of the latter billโ€™s current $3.5 trillion cost.

โ€œAmid inflation, debt and the inevitability of future crises, Congress needs to take a strategic pause,โ€ Manchin wrote in a Wall Street Journal commentary.

Sanders knows with the Senate split 50-50, he needs every Democratic vote. Reluctant to comment on Manchinโ€™s concerns, the Vermonter said in answer to another question, โ€œwe have internal problems in the Democratic Caucus and some members who are quite conservative.โ€

โ€œIt is going to be a struggle,โ€ he continued. โ€œIโ€™m on the phone day after day making sure that we can pass this legislation.โ€

Even so, Sanders expressed cautious optimism for the planโ€™s approval.

โ€œIn a month, I suspect, probably at 4 or 5 oโ€™clock in the morning, there will be a 50-50 tie and Vice President [Kamala] Harris will cast the deciding vote,โ€ he said.

Sanders chastised the media for not fully explaining the bill, although he acknowledged it would be a week or two before even his colleagues saw a more finished proposal.

โ€œThis bill is in process,โ€ he said. โ€œPeople are writing it, and Iโ€™m arguing with chairmen every day.โ€

In the meantime, Sanders is touring both liberal and conservative areas of the country โ€” he recently barnstormed the Republican-leaning states of Indiana and Iowa โ€” to promote the plan.

โ€œGet the word out whatโ€™s in the bill,โ€ he told Vermonters. โ€œLetโ€™s help rally the American people and make it hard for Congress to vote against it.โ€

Sandersโ€™ home swing featured local food and music, free Covid-19 vaccinations and speakers including environmental author and activist Bill McKibben in Middlebury, state Senate President Pro Tempore Becca Balint, D-Windham in Brattleboro, and U.S. Rep. Peter Welch, D-Vt., in Springfield.

As a fellow member of Congress, Welch acknowledged that passing the budget bill promised to be โ€œa huge challenge.โ€

โ€œThe biggest thing we have going for us is that, between the moderates and progressives, thereโ€™s broad agreement on the specifics of the bill,โ€ he said. โ€œThe dispute is about the price tag and the taxes.โ€

Welch, aiming to put the $3.5 trillion figure in perspective, noted the country spent nearly $6 trillion on wars in the Middle East and Asia over the past 20 years and another $5 trillion in tax cuts for wealthy individuals and institutions during the Republican presidencies of George W. Bush and Donald Trump.

But Welch couldnโ€™t say if Democratic leaders would have to lower the budget number to secure its approval.

โ€œThatโ€™s something Bernieโ€™s got to deal with,โ€ he said.
