Is there a better reason to break a period of Facebook silence than wishing a friend and colleague a happy birthday? Former Republican presidential candidate Mitt Romney took to the social network Tuesday to acknowledge the 43rd birthday of his running mate, Paul Ryan, marking Romney’s first post of 2013 and just his third since Nov. 7, the day after Election Day.

Romney posted:

Ann and I send many blessings and best wishes to Paul Ryan today. Join us and wish him a Happy Birthday!

After about 16 hours, the post had drawn more than 401,000 likes and over 28,000 comments, and it had been shared more than 4,600 times.

There was no word on whether Romney used Facebook Gifts to make Ryan’s birthday even more special.

Readers: Are you surprised that Romney has been virtually nonexistent on Facebook since losing the election?
