Rep. Chris Murphy, D-5th District, probably won’t get a lot of sleep in 2012, but it won’t all be because of his U.S. Senate campaign. His wife Cathy is pregnant, due with their second child in December.

As if the fundraising demands, campaign crush and electoral pressure weren’t enough. Still, Murphy said the family’s anticipated expansion shouldn’t crimp his political schedule too much.

He pointed to his 2008 election, where his first child, Owen, now 3, was born in early September, the height of the campaign season. “This one is giving us a big head start,” Murphy said of his second baby’s December 2011 due date. “But it won’t be easy.”
