Election roundup: The fisticuffs begin today

In this post-Labor Day world, it's no longer sweetness and light and pick-up basketball games on the campaign trail, the Herald warns:

The gloves are coming off in Boston's mayoral race with candidates trading accusations of ideas-poaching and flip-flopping as they head into a red-hot sprint to undercut their opponents and sway undecided voters before the 12-way Sept. 24 preliminary election.

Union guy Marty Walsh was, of course, the hit at the Greater Boston Labor Council's Labor Day breakfast, where he gave a speech.

Dan Conley also gave a speech, outlining his plan for more jobs for Bostonians. Charlotte Golar Richie also released a jobs plan yesterday.

With little money, Felix Arroyo is counting on knocking lots of doors and shaking hands at lots of T stops, CommonWealth reports. But, hey, the campaign did raise $102,000 last month.

At-large candidate Martin Keogh says the city could get more affordable housing built by setting aside the "thousands of potentially buildable lots" he says the city owns specifically for inexpensive single-family homes. A lottery would determine which eligible Boston residents could then buy the parcels and build homes on them - with help from a city fund.
