Q: How do they vote?

A. Massachusetts employs optical scan balloting without voter-verified paper ballot back-up. If the race is tight, this procedure will fuel conspiracy theories about hacked votes, ACORN machinations and the like. The upside: the votes will be counted quickly.

Q. Are there exit polls?

A. No national exit polls. We'll just have to wait.

Q. The recount procedure for Massachusetts is...

A. Here's one way for Democrats to delay certification if they think they need to. If a candidate's margin of victory statewide is less than one half of one percent, then the losing candidate has up to TEN days to petition for a recount and 15 days to submit petitions to the Secretary of State.



Q. What should we watch for tonight?

A. Coakley's margins in Middlesex County, where she's from, in Suffolk (that's Boston) and in Worcester. Also: turnout of minorities.

Q. What about independents?

A. Half of registered voters in Massachusetts are independents. Most of them lean Democratic. Most of those who've said they intend to vote lean Republican.

Q. Can Democrats really delay seating Brown?

A. Probably. There are several built-in election procedure traps, including the counting of absentee ballots and ballots from soldiers overseas. If for some reason these ballots are counted and there are no significant challenges by the seventh day after the election -- that's next Wednesday -- State of the Union Day -- then Secretary of State Bill Galvin could certify the election if he wanted to. Harry Reid, the majority leader, won't seat a senator until the secretary of state certifies him or her. But a week is too short a time frame here: under federal law, overseas votes can arrive as late as January 29. Throw in a few days for the counting of provisional ballots, and we're into early February. Then the formal certification meeting happens, which can take an extra day, depending on who is where.
