Gun veto takes on greater meaning

On Wednesday, Gov. Chris Christie vetoed a measure that would limit gun ammunition magazines to 10 rounds.

Christie contended that the bill would not end mass shootings, saying we should instead focus reforms on mental illness treatment.

The message is in line with the governor's past stance, but the issue is now even more of a political football for Christie, with eyes on 2016 and the presidency.

National gun rights groups had put pressure on him to shoot down the bill.

These are the same groups Christie will need money and support from to support a White House run.
