MANCHESTER, N.H. (AP) — Returning to swing state New Hampshire, President Barack Obama says rival Mitt Romney “took another swing and whiffed” when asked to explain how he’d pay for his tax cut plan during this week’s debate.

Obama spoke to about 6,000 people Thursday in downtown Manchester, where he stuck to the same energized line of attack he’s taken since Tuesday’s debate.

He accused Romney of failing to explain how he would pay for the cuts, and said when politicians say they will have answers after the election, it’s not because they “don’t want to spoil the secret.”

Romney’s campaign says his plan will spur economic growth, generating enough additional money to pay for the tax cuts.

It was Obama’s fifth trip this year to New Hampshire, where polls show a tight race.
