Why do we need A Republican Party?

America, Why do we need a Republican party? Given what they have done and brung over the last quarter century, You'd be very hard pressed to come up with a valid answer! Simply put, after the Reagan Renisannce, and the Bush I adminstration, the republican party went down a road, a radical path from which they've yet to return, and, as a result, America has suffered because of it! Scandal, abuse of power, corruption, conspiracy and political agenda, politically motivated and waged war,political obstruction, partisanship and so much more, the list is very long on the "Con" side as it pertains to republicanism in America. Racism, sexism, tokenism, intolerance, classism in the last 25 years these have become the watchwords and hallmarks of the republican party. And while they are the stauch advocates of "trickle down" , in the last 25 years, that is about all that has trickled down under republicans, the "isms"! So, with Post Reagan republicanism being such a clear and present failure in America, and as a political system and party, the question remains Why do we need a Republican party? Anyone?
