Vaccine enthusiasm has increased but a giant group is holding out — Republicans, Axios Vitals author Caitlin Owens reports.

• Nearly half of Republican men — 49% — said in an NPR/PBS NewsHour/Marist survey, conducted March 3-8, that they won't choose to be vaccinated when they're allowed.
• 41% of all Republicans said the same.

By contrast, 6% of Democratic men said they wouldn't get the shot.

• 25% of Black respondents, 28% of white respondents and 37% of Latino respondents said the same.

⚡ A stunning 25% of House members — all with access to the vaccine — have refused to get it, haven't reported getting it, or are avoiding it for medical reasons, Axios Kadia Goba scooped in Axios Sneak Peek.

• Although officials won't give the party breakdown, Democrats want more Republicans to get vaccinated before returning to regular voting.

COVID testing and new ventilation systems are costing school districts tens of millions, forcing poorer districts to freeze hiring and cut entire programs, Axios' Erica Pandey and David Nather report.

• Schools are having to buy oodles of masks, and provide more staff and space to reduce class sizes.

The effects are often worse in smaller, more rural districts, and in long underfunded urban districts.

• In Goreville, Ill., restrictions on the number of kids on buses became a big problem because rural school bus routes are so long, and adding buses was too expensive.

Even some Florida Democrats are wondering whether Gov. Ron DeSantis' widely panned COVID response might turn out to be right, Axios Tampa Bay's Ben Montgomery and Selene San Felice write.

• More than 32,000 Floridians have died, a number the state's leaders rarely acknowledge. But the death rate is no worse than the national average — and better than some states with tighter restrictions.

The L.A. Times compared Florida and California:

• "California imposed myriad restrictions that battered the economy ... Florida adopted a more laissez-faire approach decried by public health experts — allowing indoor restaurant dining, leaving masks optional."

On Sunday's front page, the N.Y. Times explored the positives — from the sizzling real-estate market to Florida's low unemployment rate — of an early reopening: "Much of the state has a boomtown feel."

• Florida's unemployment rate is 5.1%, compared to 9.3% in California, 8.7% in New York and 6.9% in Texas, The Times notes.

The bottom line: "Despite their differing approaches," AP reports, "California and Florida have experienced almost identical outcomes in COVID-19 case rates."

This week's seven-state swing by the first and second families is just the beginning: The White House is mapping a multi-week campaign — in red and blue states — to sell the COVID stimulus, Jonathan Swan has learned.

• Why it matters: President Biden's top advisers see the $1.9 trillion relief bill, which Biden signed Thursday, as the key to solidifying his political fortunes. The bill's strong bipartisan approval ratings supply Democrats with an opportunity to bludgeon Republicans in states that will determine elections for the foreseeable future.

What we're hearing: Team Biden has broken each day into themes emphasizing different benefits of the bill, according to an administration official familiar with the plans:

• Today, Biden will launch what he's branding the "Help is Here" campaign with a speech at the White House. Vice President Harris and the Second Gentleman Doug Emhoff will headline a launch event in Nevada. Dr. Jill Biden, a teacher, will travel to New Jersey to emphasize the impact of the bill on schools and students.
• Tuesday's theme will be "help for small business." The president will fly to Pennsylvania, and the vice president and second gentleman will visit Colorado.
• Wednesday — "help for schools" — will feature the first lady in New Hampshire and the second gentleman in New Mexico.
• Thursday — "help to stay in your home" — will highlight measures in the bill to cover back rent, protect people against eviction and aid people experiencing homelessness.
• Friday — "help immediately with direct checks" — will have Biden and Harris in Georgia.
