Tonight marks the final night of primaries this cycle, with voters heading to the polls in Rhode Island, New York, New Hampshire and Massachusetts. Here are three things to watch for in tonight’s primaries.

1. Success at the margins: Many of tonight’s contests are already foregone conclusions, but the margins still matter. Scott Brown’s campaign indicated as much when it attempted to set expectations low — below 40 percent — in a pre-primary memo. Brown, Massachusetts Attorney General and Democratic gubernatorial candidate Martha Coakley and New York Gov. Andrew Cuomo (D) are expected to win their party’s nominations tonight, but their opponents will be watching to see how many base voters defect as a potential sign of weakness in the general election.

2. Will Rep. John Tierney survive? Tierney is the last House incumbent this cycle at real risk of defeat, but his loss to primary challenger Seth Moulton could turn out to be a boon for Democrats, some of whom believe Moulton would be a stronger general election candidate than Tierney. Local Democrats note that it’s telling national Democrats and Democratic groups have done nothing to prop up Tierney in the final stretch of his campaign, which they’ve read as an implicit acknowledgment they’d be happy with either Democrat as their nominee.

3. Will the rising star or the safe bet take on Rep. Annie Kuster this fall? The Republican primary in New Hampshire’s 2nd District has grown increasingly nasty as rising GOP star Marilinda Garcia battles former state Sen. Gary Lambert for the opportunity to take on one of Democrats’ most vulnerable incumbents this cycle. Garcia has emerged as the front-runner in the final weeks of the race and sought to moderate her image, but Republicans have privately expressed concerns that some of her more conservative positions could cause them headaches in the general if she wins the nomination.

“I have never really sat down with my great friends, with my close friends that I’ve known for 30 years, and said, ‘What do you think?’ Until you do that, you can’t even think about it, because I think most of ’em would probably say no,” he said. “You know, I tried to run for president once. ... It was really brutal.”

He also says he’s thinking about writing a book after former Speaker Newt Gingrich (R-Ga.) encouraged him.
