Rasmussen Reports says Gov. Deval Patrick is virtually tied with his Republican opponent, Charlie Baker:

The latest Rasmussen Reports telephone survey of Likely Voters in the state finds incumbent Democratic Governor Deval Patrick with 46% support, while Republican challenger Charlie Baker gets 44% of the vote. Democrat-turned-Independent Tim Cahill remains a distant third with six percent (6%). Three percent (3%) prefer some other candidate, but just one percent (1%) is still undecided.

I followed Baker on the campaign trail a few weeks ago. See the write-up here.
