(AP Photo/Mark Lennihan) (Newser) – 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.
