A second poll in a row has found state Rep. Marty Walsh leading City Councilor John Connolly in the Boston mayoral race.
Forty-six percent of likely voters back Walsh, compared to 43 percent who support Connolly, according to the Suffolk University/Boston Herald survey, out Friday.
That lead is within the poll's margin of error of 4.2 percent.
The survey found 9 percent of voters are still undecided. The election is Tuesday.
The Suffolk/Herald poll follows a UMass-Amherst poll, out Wednesday, that had Walsh with a seven-point advantage over Connolly. The UMass survey — which had a larger margin of error, at 5.2 percent — was the first of the race to show Walsh ahead of Connolly.
An earlier Suffolk/Herald poll, in early October, found Connolly with a seven-point lead.
The new Suffolk/Herald poll, of 555 "very likely" final election voters, was conducted Oct. 29-31.
A separate Suffolk/Herald snap poll of 300 East Boston residents found narrow support for a proposed casino at Suffolk Downs — with 47 percent approval and 42 percent disapproval.
A WBUR/MassINC survey, out Thursday, had those casino numbers flipped, with 46 percent of East Boston voters against the project and 42 percent in support.
