Dont be so quick to criticise others when you live in a conservative state with a DEM Senator who is running for President. Have you been sitting on your ass waiting for the ideologically pure candidate to arrive on his white horse?
Since you want to talk about IN politics...
The GOP leadership in Indiana has wasted many opportunities, IMO. They put most of their energy and money into winning the gubernatorial race (which Republican Mitch Daniels won handily), ignoring the US Senatorial (which DLC-lib Bayh won) and the 7th district Congressional race (lefty Julia Carson won). These races were winnable, yet in both cases we had poor GOP candidates. Even worse, as if that were not enough to assure defeat, neither GOP candidate got a dime from the state or local party, and got no assistance from the well-run Daniels campaign.
I did volunteer and contribute money to try to secure a different outcome. But, leadership matters, as does the essential management function of efficient resource allocation. I don't belong to the inner GOP circle, and have no influence over these decisions. Given my (politically prominent Democratic) family history, I would NEVER be trusted in such a position, despite my lifelong hardcore conservative orientation. Even my nugatory volunteer activities were viewed with suspicion and distrust. I saw incompetent campaigns (in one, the GOP candidate burned a copy of the local paper in effigy in front of the news building when they endorsed his opponent), lacking even the most basic political instinct or management skill, and was powerless to "help" except in an inconsequential, functionary capacity (and also though my generous financial succor, natch).
So, rather than "sitting on my ass", I've wandered around a bit, and become disenchanted through a lifetime of political involvement. Anyway, I prefer to type standing.
I do not insist on ideological purity, but if neither party is aligned with me on basic principles, then I don't have a stake in what is simply a power struggle between two interest groups.
