Via kos, here is the latest State House poll on the MA governor's race.  Romney's favorable/unfavorable has dropped from 54-37 to 47-43 since September.  He trails (AG Tom) Reilly by 36-52, (SecState Bill) Galvin 41-46, and leads (former US atty Deval) Patrick 42-40.  (Note that Galvin is not yet a declared or particularly active candidate.)  All three Dems crush Lt. Gov. Kerry Healy (25-56,28-49, 32-44).

Some of the comments on the Kos thread address the state of Patrick's campaign -- the claim is that he is raising adequate money but spending it fast developing a campaign infrastructure.  To get on the primary ballot he needs 15% or more of the vote at a June convention that will be packed with activists -- this seems not too difficult a hurdle comapared with expanding his name recognition to compete with Reilly in the September primary.

Romney has pledged to reveal his plans "during the fall".

Update: Globe columnist Adrian Walker has this sympathetic look at the campaign in today's paper. I think it's a promising sign that Patrick's campaign website has already linked to the Globe story.
