WESTCHESTER COUNTY, N.Y. -- The campaign for New York state's 247 Democratic delegates will be in full swing this week.
Hillary Clinton of Chappaqua will make a campaign visit to Purchase College in Harrison on Thursday, afternoon while presidential primary rival Bernie Sanders, a U.S. senator from Vermont, will visit the South Bronx in the morning.
New York's primary election for both major political parties is on April 19.
Clinton, a former New York senator, First Lady and Secretary of State, held an "organizing event" Wednesday morning at the Apollo Theater in Harlem.
According to her campaign, "Clinton will hold events in New York City and Westchester where she will discuss her plans to raise incomes and get results for all communities, keep Americans safe, and bring the country together."
Clinton's SUNY Purchase event begins at 1 p.m. on Thursday. She announced her bid for U.S. Senate at Purchase College before more than 2,000 students in 2000, as recorded in this CNN transcript.
Greenburgh Supervisor Paul Feiner, U.S. Rep. Nita Lowey of Harrison and Westchester County Legislator Ken Jenkins of Yonkers are among local Democrats planning to attend.
The Republican presidential primary also is on April 19, with Donald Trump -- who owns an estate in Bedford and golf clubs in Briarcliff Manor and Hopewell Junction -- enjoying a comfortable lead in political polls.
A Siena College poll conducted early this month showed Trump with a 27-percent lead over Ohio Gov. John Kasich in New York.
Kasich held a town hall event Wednesday in Howard Beach, Queens. His campaign plans to go to Long Island next week.
Kasich and Trump -- a Queens native -- are invited to speak at a state GOP fundraiser on April 14 in Manhattan.
Republican Ted Cruz, a U.S. senator from Texas, cancelled a stop in Brooklyn to focus on campaigning in Wisconsin for Tuesday's primary there.
Clinton spoke Wednesday at the Apollo Theater on West 125th Street where she discussed "her plans to raise incomes and get results for all communities, keep Americans safe and bring the country together," according to the Clinton campaign.
Sanders' Thursday visit to the South Bronx includes a discussion of "a wide range of issues, including getting big money out of politics, his plan to make public colleges and universities tuition-free, combating climate change and ensuring universal health care," according to his campaign.
Sanders' door-to-door campaign is getting assistance from the labor-backed Working Families Party.
Upstate GOP leaders said Trump garnered early support there when he weighed a gubernatorial run against Andrew Cuomo of New Castle in 2014. Cuomo defeated Westchester County Executive Rob Astorino of Hawthorne in that statewide race.
