Donald Trump has a big lead in polling in his home state of New York, but he won't be getting the votes of two of his biggest advocates there: His kids.

 Trump conceded Monday that two of his children — Eric and Ivanka Trump — failed to register as Republicans in the state in time to be eligible to vote for him in New York's April 19 primary. 
 
 "They were unaware of the rules and they didn't register in time," Trump said on Fox News. "So they feel very, very guilty. They feel very guilty but it's fine." 
 
 The deadline for new voters to register to vote in New York's closed primary was March 25, and the deadline to change party affiliation was back in October. 
 
 "Eric and Ivanka, I guess, won't be voting," Trump said. 
 
 NBC 4 New York reports that, according to New York's public Voter Registration Database, both Eric and Ivanka Trump are registered to vote but not enrolled in a political party. 
 
 Trump's campaign has been plagued in recent weeks by poor organization in local and state-level Republican conventions, where delegates to the Republican National Convention are selected. 
 
 In several states over the weekend, the delegates chosen at the party gatherings were Ted Cruz's loyalists, who could support the Texas senator on the convention floor if the nomination race goes to a second ballot. ||||| Eric Trump and Ivanka Trump attend a news conference in New York, May 1, 2014.

 Donald Trump’s three oldest children have campaigned with their father and served as surrogates during the presidential race. But only one of them is actually a member of the party Trump hopes to lead. 
 
 Records from the New York State Board of Elections show that neither Ivanka Trump nor Eric Trump is enrolled in a political party. Trump’s oldest son, Donald Trump Jr., is a Republican. 
 
 Both Eric and Ivanka Trump have also donated money to Democrats. Campaign finance reports show Eric gave $1,000 to Sen. Chuck Schumer, D-N.Y., in 2010. Eric has made 11 other contributions totaling over $138,000 that all went to Republican candidates. 
 
 Ivanka’s campaign contributions have a more bipartisan bent. Records show she has donated over $240,000 to both Democrats and Republicans. Ivanka has given money to Schumer, Sen. Cory Booker, D-N.J.,, Sen. Kirsten Gillibrand, D-N.Y., Rep. Donald Norcross, D-N.J., District of Columbia Delegate Eleanor Holmes Norton, and Hillary Clinton’s 2008 presidential bid. On the Republican side, Ivanka has given money to the presidential campaigns of Mitt Romney and Sen. John McCain, R-Ariz. In 2010, Ivanka gave $2,000 to Carly Fiorina’s U.S. Senate campaign. Fiorina ran against Donald Trump in this year’s Republican primary and the pair had several contentious exchanges. Fiorina ended her presidential bid in February and endorsed another Trump rival, Sen. Ted Cruz last month. In addition to giving money to both Republican and Democratic candidates, Ivanka has donated to committees benefiting both parties. 
 
 Neither Ivanka and Eric Trump responded to requests for comment from Yahoo News. The Trump campaign also did not respond to a request for comment. Along with Donald Jr., Ivanka and Eric, Trump has two younger children. Tiffany Trump, 22, has not been as active in the campaign as her older siblings and Yahoo News could not find voting records for her. Trump’s youngest son, Barron, is just 10 years old. 
 
 New York State Board of Elections records show that both Trump and his wife, Melania, are members of the Republican Party. But Trump has a rather unusual relationship with the Republican Party, and has sometimes been at odds with the Republican National Committee. Like his daughter, Trump has given money to members of both parties.
– Donald Trump won't be able to collect two easy votes in New York's primary later this month: Daughter Ivanka and son Eric failed to register in time and thus can't cast votes on April 19, reports NBC News. "They were unaware of the rules," Trump said on Fox News. "So they feel very, very guilty. They feel very guilty but it's fine." Yahoo News reported last week that only oldest son Donald Jr. is a registered Republican and that both Ivanka and Eric have previously donated to Democratic candidates. Trump has two younger children, Tiffany, a college student not active in the campaign, and a son, Barron, who's just 10.
