(CNN) - Voters in five states will head to the polls on Tuesday after a three-week lull in the Republican presidential primary season, a time in which Mitt Romney essentially secured his party's nomination.
Connecticut, Delaware, New York, Pennsylvania and Rhode Island will hold primaries, with a total of 204 delegates at stake.
Here's a glimpse of the nuts and bolts for Tuesday's contests.
Wilmington, Del. (CNN) – As the Republican field winnowed Tuesday, Mitt Romney made an appeal to a voting bloc key to any candidate's success in November: women.
Though the day's headlines revolved around a decision by former Sen. Rick Santorum to suspend his campaign, Mitt Romney barreled forward with a push against Democrats as to who could best appeal to female voters.
(CNN) – Speaking publicly for the first time about Rick Santorum suspending his campaign, Mitt Romney on Tuesday night expressed relief over his former opponent's decision.
"This has been a, a good day for me," Romney said at a rally in Delaware, as a large crowd cheered him on. "Sen. Santorum has decided not to proceed with his campaign."
Washington (CNN) - Conservative challenger Rick Santorum announced Tuesday that he is suspending his Republican presidential campaign after a weekend of "prayer and thought," effectively ceding the GOP nomination to front-runner Mitt Romney.
Santorum made his announcement after the weekend hospitalization of his 3-year-old daughter Isabella, and in the face of tightening poll numbers in Pennsylvania - the state he represented as a U.S. senator - ahead of the April 24 primary.FULL STORY
(CNN) - Vice President Joe Biden now has a landmark bearing his name. On Saturday Amtrak renamed the Wilmington, Delaware, train station Joseph R. Biden Jr. Railroad Station in honor of the vice president, who rode the train from Wilmington to Washington, D.C. regularly for 36 years as Delaware's senator.
(CNN) – Republican Christine O'Donnell sounded a defiant tone the day after losing her Delaware Senate bid to Democrat Chris Coons, calling her loss a "symptom of Republican cannibalism."
"In other areas, where the establishment Republican didn't win their primary, the local Republican parties united right away. Solidarity goes a long way. Unfortunately, that never happened in Delaware," O'Donnell said during an interview on CNN's American Morning.
(CNN) – The thing about Delaware is: it's no Kentucky.
The Tea Party's first Senate loss of the night may be no big surprise - the only question heading into tonight's been how big a victory margin Chris Coons would capture over Christine O'Donnell. But the exit polls lay out the political and demographic roadblocks facing any Tea Party favorite here.
(CNN) - Democrat Chris Coons has beat out Tea Party-backed Republican nominee Christine O'Donnell in the race to fill Vice President Joe Biden's old U.S. Senate seat, CNN projects. Democratic Sen. Ted Kaufman, who replaced Biden, is retiring. Projections are based on CNN analysis of exit poll data.
Dover, Delaware (CNN) - "Can I ask for your vote today? I want to fight to keep your taxes low," Christine O'Donnell told voters as they arrived to cast their ballots at Dover High School. O'Donnell the Republican nominee for the US Senate has been traversing the state today in an RV.
She began the morning casting her own vote in Wilmington before heading south. Three miles away Chris Coons the Democratic nominee walked into the voting booth with his young son to cast his vote. And at a third polling place a stone's throw away, Vice President Joe Biden returned to his home town to cast his vote before a throng of reporters.
(CNN) – It appears differences have been set aside between Delaware Republican Senate candidate Christine O'Donnell's campaign and Delaware 28 executive producer Tim Qualls as a 24-minute commercial by the candidate is now running on the station.
