New Hampshire and Iowa have historically been the first states to make their choice in the state-by-state battle to pick presidential candidates in November’s election. Iowa voters decide today and New Hampshire next Tuesday. Kids may not be able to vote but every politician knows the value of a picture with a cute baby. And in New Hampshire, many parents seem determined to get their children involved in the election process. Some children are already veterans of the candidate meet-and-greet. “I used to hate it when I was little but not any more, I like going now,” said 14-year-old Bjarna O’Brien after meeting Republican presidential hopeful John McCain at a diner in the town of Derry. By now, Bjarna has developed opinions which she says are only partly shaped by her mother, who home schools the sisters. She says McCain is not tough enough on illegal immigration and that abortion is “worse than murder.” John Kelly, an 11-year-old who met McCain by chance at another New Hampshire diner on Tuesday, talks fluently about the need to do more for the middle class and about Republican hopeful Mitt Romney’s record of raising taxes.
