Political party shifting?

[5280]

I think after the 2012 elections is the start of both political parties shifting positions.  

The Republicans becoming more Libertarian, open to legalizing drugs, civil unions, non-intervention, more focused on economy and business.  I've noticed alot of Tea Party people and social Conservatives are not thrilled with Romney and could form a new party in another decade or something.

Democrats appealing to working class hispanics, unions, the poor, and possibly catering to religious right (catholics)

What's your say?
