The way that Politics work is each party has a hard core support of roughly one third of the people that bother to vote. ERGO, to win an election, each party has to go after the one third, roughly, that will vote either way w/o regard for the party.
The above is true Nationally, but less so in individual States.
A politician out of power is a pathetic thing, to be avoided if at all possible... THEREFORE it is not always possible to depend upon what a politician says as the truth. The Politician is apt to say to the extent that he can, what he believes that you want to hear...truth or not.
To keep their power base, they have to stay mindful of the position of their own party, which they have to depend upon for unwavering support. But try to sell to the "middle", which cannot be depended upon as unwavering support, that what they do is good.
To get elected is the thing. The ONE thing.
