After campaigning at arm’s length, Senator Scott Brown and the Democrat trying to unseat him, Harvard Law School professor Elizabeth Warren, met face-to-face tonight for the first of four debates in their hotly contested race.

Boston.com, BostonGlobe.com, and “Political Intelligence’’ provided this live blog to recap the run-up to the event, the candidate back-and-forth, and the post-debate spin.

Read below for a recap.

The debate itself was preceded with some drama amid questions about whether Brown would be able to break free from Capitol Hill to return to Boston. He left the capital at mid-afternoon and arrived at the WBZ-TV studioes at 6:20 p.m. EDT. The debate began at 7 p.m.


Brown, the Republican incumbent, said earlier this week he planned to use the debate to highlight the differences in the political philosophies he and Warren embrace, as well as his interest in job creation and what he labeled her “radical, Occupy Wall Street’’ views.

Warren, trying to win seat back for the Democrats after Brown won a 2010 special election to replace a party icon, the late Senator Edward M. Kennedy, said she planned to underscore where she and Brown would diverge on votes she considered important for Massachusetts.

She highlighted votes he cast on summer jobs programs, as well as his support for what she termed oil industry subsidies.

The hour-long debate was moderated by Jon Keller, the political analyst for WBZ-TV and a veteran observer of the Massachusetts political scene.

The candidates will also debate next month in Lowell, Springfield, and Boston.

6:40 p.m. – In testament to her union backing, Warren benefitted from a big labor turnout outside the WBZ-TV studios. Her signholders vastly outnumbered the smattering who turned out for Brown.


One hardy Brown backer, Jack Patts of Quincy, said, “I like Scott. I’ve been following him for years.’’

He said he liked Brown’s bipartisan work.

“The crossover thing,’’ said Patts, a 60-year-old insurance claims adjuster. “It’s just getting too crazy, the Republicans and the Democrats. He’s doing the right thing.’’

Joe McDermott, a union carpenter from Dorchester, helped hold a sign for Warren.

“Elizabeth Warren has done more for the working people and working families than Scott Brown,’’ said McDermott, 55. She’s a consumer watchdog. The Republicans blocked her from heading the [Consumer Financial Protection Bureau]. She’s going to be the Democrats’ revenge – in the Senate.’’

Warren goes back to the three jobs bills, recalling a conversation with a carpenter.

“Those are three jobs bills that would have supported jobs here in Massachusetts,’’ she says. They would have been paid for with “fractional’’ tax increase on those making over $1 million.

“We have work to be done, but Senator Brown is lining up with the Republicans to vote ‘no,’’’ she says.

—

7:12 p.m. – Brown is clearly bristling and eager to get at the professor. She is more calm, unrattled as he goes after her and as she faced first question on sensitive topic of her claim of Native American heritage.

Brown retorts that if Warren wanted to pay more in taxes, she could have elected to do so on her state tax form and chose not to.

Brown said he doesn’t support Big Oil, but the motorist who is suffering at the gas pump.
