Rep. Paul Ryan (R-Wisconsin) has put forth a budget proposal that has some congressional democrats cheering, almost giddy in fact.  Why?  The liberals think the Ryan plan, which calls for 'an end to Medicare as we know it' and deep cuts to most social programs has democrats thinking this could be their ace in the hole.  They think the 'threat' of republican cuts will spur voters, particularly the elderly and those who rely on public assistance almost entirely, to cast their ballots for democratic candidates.  One of the more interesting aspects of the Ryan plan is that it calls for the creation of two tax brackets, 10 percent and 25 percent; this would eliminate the six brackets that currently exist.  It appears congress, or at least Ryan and his congressional supporters, are moving us closer to the concept of a flat tax system.  It's a baby step, but a step nonetheless.
