As many no, I am no fan of the coalition deal. But it appears that my worst fears might be proved right about the capitulation of Lib Dem MPs to David Cameron when you see that Lib Dem poll ratings are falling whilst those for the Tories are increasing.
It is an obvious and logical conclusion for electors to decide that if the coalition does it a good job then they should support the larger partner in the coalition because as the larger partner, they deserve more praise than the junior partner. Similarly, it is hard for the Lib Dems to claim that people should not vote Tory as the Lib Dems are backing the Tories.
Don't be surprised to see Lib Dem rating fall further in the near future.
