I (believe) what the above article implies anyway, is that there is a section of Republicans in Maine who are unhappy with the current focus of the party, in that the party seems to be for a series of things which the GOP has traditionally been opposed to.
To make it simple, the 13 are for traditional GOP positions.
They are leaving the GOP because they do not like the new big-government big-brother positions which have been taken, and want to return to the traditional GOP positions.
They feel their ability to support what (had) been traditional GOP positions has been lost in the current GOP, so they are quitting the GOP.
In effect, they are throwing off their GOP stripes in protest against a state GOP which is too much like democrats?
Is that what is happening here?
The Maine GOP stole Ron Paul’s 2012 presidential primary victory.
