(CNN) - It looks like Tuesday is going to be wild.
1. President Barack Obama announced Friday he plans to address the nation from the White House on his proposal to take limited military strikes in Syria.
2. It's primary day in the New York City mayoral race. Most eyes will be on the Democratic primary Tuesday as a crowded crop of contenders battle for their party's nomination in the mayoral race. Most recent polling shows Public Advocate Bill de Blasio with 43% support, with former Comptroller Bill Thompson and City Council Speaker Christie Quinn falling behind. Meanwhile, former Rep. Anthony Weiner is in the single digits. If a candidate doesn't pass the 40% threshold, the primary turns into a runoff between the top two candidates. Polling shows the Democratic nominee will likely best the Republican nominee during the general election in November.
(2.5 Also taking place Tuesday are the primaries for the New York City comptroller race. Normally it's not a contest that makes national headlines, but this time former New York Gov. Eliot Spitzer is running for the office, five years after resigning his governorship amid a prostitution scandal. He squares off Tuesday against Manhattan Borough President Scott Stringer in the Democratic primary. While Spitzer commanded the lead for a while, Stringer has caught back up in recent polls and the race heads into Election Day in a statistical tie, with Stringer slightly ahead.)
3. Hillary Clinton is scheduled to give a big speech. The former secretary of state said she would talk about "transparency and balance" in national security policies at an event where she's slated to receive an award in recognition of her career in public service. Former Florida Gov. Jeb Bush, chair of the National Constitution Center, will award the medal to Clinton during the 25th annual Liberty Medal ceremony at 7 p.m. ET. The ceremony will take place at the National Constitution Center on Independence Mall in Philadelphia.
4. Colorado holds recall elections. Two Democratic state lawmakers are on the ballot after they voted in favor of new gun control measures. The race is loaded with national implications, as supporters of the recall hope the election sends a cautionary message to lawmakers in other states. Gun control supporters, meanwhile, hope the senators will survive the effort and prove that recalls aren't an effective tactic in intimidating lawmakers in the gun control debate.
5. The new iPhone is likely to be announced. Apple is hosting an event in Cupertino, California. The company has all but confirmed it will be launching a new iPhone, but invitations for the event do nothing to quell the rumors. The invite is bursting with bright pastel bubbles in the same color scheme that's used for the iOS 7 operating system on which its new iPhone will likely run. Along with a new iPhone, reports are split on whether a refreshed iPad is also on tap.
